He is the prototype of the high-level uncle "Dumbo" in the current movie "Underworld", who once went undercover in the police force, and Chen Huimin was his brother-in-law.
He is also the "king-maker" of the gang "Katsuwa", and has a veto power within the community, which the Jianghu people call "Katsuwa Regent".
He is the super boss of Hesheng and his uncles, Li Guohua.

Lai was born in 1935 in the slums of Sham Shui Po in Hong Kong, where the streets are full of sewage and houses made of wood and tin. Although Li Guohua's family lived in this environment, his parents paid more or less attention to education, and they also read books for several years when they were young.
But after all, "the children of the poor have long been in charge", and at the age of 15, Li Guohua learned the skills with his master and became a hydropower worker.
Li Guohua, who entered the society in his early years, needed to deal with people all year round because of his work position, of course, most of them were low-level people, and he also knew many people of the three religions and nine streams at this time. Later, he worshiped under Zhen Guolong, the "First Old Top", "The First Sitting Hall", and "Underworld God of War".
Although Li Guohua is not good at fighting, killing and killing, he has a good personality, is humble, and has a flexible brain, earning a lot of gold and silver for the boss Zhen Guolong, and is deeply appreciated by Zhen Guolong.
In 1956, half of Hong Kong Island was paralyzed by the "Double Ten Riots" caused by 14K, and since then, Asir has launched a "heavy blow" against the underworld forces for many years, and there has been a vacancy in the hands of the people.
And "there are policies at the top and countermeasures at the bottom", the gang forces sent Ma Zai to the police station to apply, and became the gangster's undercover in the police station.
In 1962, Lai Kwok Wah was 27 years old, and because of his agility, the boss Zhen Guolong entrusted him with a heavy responsibility and was sent to the police academy to apply. Coincidentally, Chen Huimin, who was more than ten years younger than him, was also training in the police academy at this time, and the two became friends at this moment.
Because Chen Huimin came relatively early, Li Guohua often called Chen Huimin "master brother" in front of people.
To discuss the status of the jianghu, Li Guohua is no less than Chen Huimin, and this "master brother" can really see Li Guohua's humility.
After graduating from the police academy, both Lai Kwok Wah and Chen Huimin became prison guards, which is often referred to as "Liu Ji" in the gang. In the police force, Lai Kwok Wah was often ridiculed as a "stupid soldier", always pretending to be stupid and stupid. In fact, because his gang identity is more sensitive, these are all pretended to be in case they are recognized.
In the early 1960s, the boss Zhen Guolong was elected by the gang as the first member of the "Heshenghe" to sit in the museum, under the advice of Li Guohua, Zhen Guolong did not participate in the "yellow gambling and drug" like other gangsters, but took a long-term route and operated a legal mahjong hall, and Zhen Guolong had seventeen mahjong halls on hand during the peak period, and Li Guohua, as a proud disciple, was the manager of these casinos.
The affairs of the gang are inseparable from him, during the day he has to go to work in the police force, and at night he has to return to the gang to work, shuttling between black and white, and the role switch is very successful.
But because of this, there is often not enough time to rest, often stepping on the time point into the police force, on the road is driving while getting dressed. Therefore, he was often reprimanded by the leader and deducted his salary, but Li Guohua always "played haha" with the leader, and after that, he was not much reprimanded, but the money should be deducted or deducted.
In fact, Lai Kwok Wah's salary in the police force was very high, at that time a bowl of wonton was a dime, and Lai Kwok Wah's salary in the police force was as high as more than two hundred yuan, and his income was already good compared to ordinary people. Not to mention that he has more oil and water in the gang.
When he was undercover, he also got a lot of intelligence for the gang, and before long, because the rapid rise of 14K was already a threat to the development of Heshenghe, Li Guohua resigned and returned to his "main business". During this period, the identity was not recognized by Asir, which shows that Li Guohua's emotional intelligence is superb and his acting skills are in place, just like Andy Lau in "Infernal Affairs".
After returning to the gang, Li Guohua's status has also improved, from the original "Four Nine Boys" directly crossed the level to "white paper fan". That is to say, from the "primary horse boy" to the "military division level" figure who controls the party.
After the status is promoted, of course, it is necessary to make a greater contribution to the gang. On the one hand, he resisted the invasion of 14K and other gangs, and he was deeply rooted in the true legend of the boss Zhen Guolong, who was a guerrilla in his early years, and when he clashed with other gangs, he rarely tried to solve problems in a tough way, but used guerrilla tactics to drag the other side tired.
On the other hand, it is to open up the territory for the gang. In the late 1960s, Lai Kwok Wah also opened his own mahjong hall in Yau Ma Tei, and expanded his mahjong business to Yuen Long, Hong Kong Island, the New Territories, Kowloon and other places. Some of the territory is still outside Kazukazu's sphere of influence, but they get along well with other gangs. At that time, Hong Kong mahjong halls were very popular and legal.
In addition, Li Guohua also runs his own Venus Restaurant, which serves as the staff of Ma Zai to eat and drink, and has become the canteen of the ma zai, eating and drinking enough to do things for Li Guohua, which can be described as selling his life.
Li Guohua has made a lot of money for the community and has a superb ability to absorb gold.
It can be seen that Li Guohua's ability to distribute benefits, industrial management and control of personnel is very strong.
Of course, no matter how perfect a person is, there will be people who can't deal with it.
In the 1970s, Li Guohua set his sights on the "Women's Street" in the Yau Tsim Mong area, which was very prosperous, had a strong commercial atmosphere, and had plenty of oil and water.
After Li Guohua took this territory, Zhen Guolong slowly let go of Li Guohua and became the main person in the gang. However, because of the "Women's Street" incident, it was tied to the "Crooked Mouth Energy" of the United Industries Club who was entrenched in Jordan.
Even "Crooked Mouth Noh" announced to the outside world: "As long as the people who are Katsuwa set foot in Jordan (the territory of the United Nations Agency), they will put a red knife into a white knife." ”
It happened that once Li Guohua and the same door passed through Jotun, "crooked mouth can" also do what they said, directly sent people to chase them, the other party copied a forty-meter machete from the sky, Li Guohua ran forty-one meters to avoid and was also locked by the knife gas, fortunately, he ran fast and did not die on the spot.
But Li Guohua was also injured, and until now, the wound on his face from the corner of his mouth to the sideburns was still faintly visible.
"Crooked mouth energy" was also famous for a while. And Hesheng and Zhen Guolong were very angry, angry that the "crooked mouth can" not only hit the face of the gang, but also hurt his beloved disciple, directly breaking the face.
Besides, if the gang wants to develop, the "crooked mouth energy" is really an obstacle to being entrenched here, and the gang has met repeatedly, and the result is that the "crooked mouth energy" must be eradicated.
During his hospitalization, Lai Guohua was not allowed to take revenge on the "crooked mouth", and Zhen Guolong successively contacted Ho Sheng and various church people, as well as people and horses in the New Territories, Hong Kong Island, and Kowloon. The so-called "son of heaven is angry, and millions of corpses are ambushed."
A month later, under the leadership of the two masters and apprentices, Hesheng and five or six hundred people Ma Qiqi set out to surround the "crooked mouth can" Jotun Guan Chung Street.
In the face of Heshenghe's momentum, "Crooked Mouth Neng" and his associates of the United Society were afraid, and the momentum was shorter by more than three points, and after requesting the support of the headquarters of the United Society, the support of the Headquarters of the United Society was obtained: "The other side is big, and the love can not help", the "Crooked Mouth Neng" was even more directly subdued, and the men abandoned their weapons and surrendered on the spot.
Leaving a "crooked mouth can" one person to prostrate on the spot and admit his mistake, at that time, Li Guohua was still wrapped in gauze on his head, and the scene was really funny.
Li Guohua in the storyline is a bit like Lu Xiaojia, the son of the warlord on the beach, who was first violently beaten by the rogue leader Jin Rong, and then lu Xiaojia led the troops to take Down Jin Rong, making him prostrate and admit his mistake.
In addition to kneeling down to apologize, "Crooked Mouth Energy" also took out 100,000 yuan of medical expenses to pay Li Guohua, and the 100,000 yuan in the 70s was estimated to be more than two million yuan compared with the present. And "Crooked Mouth Can" also gave up jordan's territory, after all, kneeling down to apologize is no longer able to gain a foothold in the jianghu. In ancient times, this was the so-called "land-cutting indemnity".
Seeing that the gang's face was recovered, the territory was also taken down, and the "crooked mouth can" also lost 100,000 yuan, and the two masters and apprentices "had to spare people and spare people" and let go of "crooked mouth energy".
After all, other purposes have been achieved, and even if the "crooked mouth energy" is removed, Li Guohua's face cannot be restored, and the two masters and apprentices have very similar personalities, and they are people who will not do things to the extreme.
After this battle, Lai Guohua's reputation was greatly enhanced, and Jotun's nightclubs and gambling stalls belonged to him, becoming the underground king of Jordan.
At the end of the 70s, the boss Zhen Guolong retired, and at the same time handed over the big stage of the jianghu to the descendants of his subordinates. Li Guohua and Zhen Guolong are similar in age, and they also have no intention of competing for the sitting hall, although they did not become a sitting hall, but they are more powerful than sitting in the sitting hall, because Hesheng and the previous sitting halls, many of them are from his disciples.
And when he chose to sit in the hall, he had a veto. Therefore, the Jianghu people called him "the king of victory and peace" and "the prince of victory and regency". At his peak, he had thousands of protégés and no one could have had an unparalleled influence on the community.
For example, "Shanghai Boy" Guo Yonghong is the sitting hall from 1998 to 2000, he is very open in the political and business circles, smooth in his dealings, and Jimmy played by Gu Tianle in "Underworld 2 : Peace is Precious" is based on him.
"Muay Thai An" Chen An, sitting in the gym from 2004 to 2006, one-handed Muay Thai for 20 years of skill, who can catch it?
"Fei Jian", the dry son of Lai Kwok-wah, served from 2013 to 2016 as Hesheng and "Rolling Numbers", that is, managing the accounts of the community, at the same level as the Zaguan.
"Azu", The disciple of Lai Kwok Wah, served as a katsukatsu from 2016 to 2019.
Lai Kwok-wah is humble and gets along very well with his neighbors, and "peace is precious" is his motto. "A man who does not cause trouble, has credit, and loves his family" This is the high evaluation of chen shenzhi of 14K "Ciyun Mountain Thirteen Taibao".
And so many fierce people in the protégés are acting as a blessing in the outside world, and they are mostly respectful in front of Li Guohua. As he grew older, Li Guohua also retired to the jianghu.
In 2005, Li Guohua was hospitalized for a stroke, and he had strong willpower to overcome the disease, and after being discharged from the hospital, he was no different from a healthy elderly who paid attention to health, and usually worked out, drank morning tea, and enjoyed the joy of heaven at home.
In 2015, Li Guohua's 80th birthday, since retiring, he has rarely held a birthday banquet, which is a rare day for people from all walks of life. Macau's "father of the gambling boat" Ip Shou, famous movie star Chan Wai Man, 14K "godfather" Beard Yong, as well as Famous Hong Kong doctors, well-known lawyers, and even police officers were present to celebrate the birthday. The Kazukatsu and gangs were almost always present, and the aforementioned fierce men were mostly in front of the saddle and greeted the VIPs.
Originally, although Li Guohua was in a high position, he was quite low-key, but in 2014, when a student of shuren University's journalism department interviewed him, Li Guohua unexpectedly accepted. In the interview, the jianghu past he talked about has become a hot topic among many netizens, in addition, because of his kindness, some netizens also called him "Grandpa Xiao Maruzi".
Of course, joining the gang that year may be involuntary to survive, there are not many people who can die well, more are killed, or spend the rest of their lives in prison. With the development of society, the gang is already in the twilight of the west mountain, and there is no future. Then there is the fact that people who are modest and low-key can often live longer.
