In 1904, Li Decai was born in Luxi County, Pingxiang City, Jiangxi Province, and his family had been farmers for generations, and at the age of 22, Li Decai resolutely joined the local peasant self-defense army.
1930 was a turning point in fate for Li Decai's life, Mr. Peng led the team to Pingxiang, Li Decai saw the disciplined Red Army team, which made Li Decai full of pride, and soon after entered the Red Army team and officially embarked on the revolutionary road.

After joining the Red Army, Li Decai was modest and studious, trained hard, had excellent shooting talent, and after research and hard work, he practiced extremely amazing shooting skills, and was called a sharpshooter by everyone.
In 1955, he was awarded the rank of colonel, and he participated in five anti-"encirclement and suppression" campaigns, the War of Liberation, the War to Resist US Aggression and Aid Korea, and made outstanding military achievements.
The Long March of the Central Red Army began to enter the Sichuan region after a long journey of hardships and obstacles. According to the plan, the Central Red Army continued to go north and reached the Red Fourth Front Division in the Chuankang area in advance; the Central Red Army had the Dadu River in front of it and the pursuing enemy in the rear, and in order to successfully meet the division in the north, the Central Red Army could only advance towards the Dadu River and prepare to cross the river and enter the northwest sichuan region.
The Central Red Army has to face a huge problem, how can it cross the Dadu River?
Dadu River is an insurmountable graben, both sides are cliffs, many whirlpools under the water, the water is turbulent, dangerous, wide up to a thousand meters, the depth of the water is about seven to ten meters, known as "natural danger", the river is unfathomable, rushing, coupled with the turbulent whirlpool, always revealing the jagged and vicious reef at the bottom of the river, shocking.
However, only by crossing the Dadu River could it win a glimmer of vitality for the Central Red Army, and finally anshun field was selected as the location for crossing the river.
The advance team of the Red Army rushed all the way to Anshun Field in heavy rain, and the Han Huaijie Battalion of the Sichuan Army guarding The nearby Anshun Field thought that the Red Army was going to cross the river from the direction of Dashu Fort, and with the heavy rain falling from the sky, it was determined that the Red Army would not arrive at Anshun Field at this time, so it was defenseless.
The red army advance team members rushed to the opposite shore of the heavily guarded shore in a small boat in the turbulent waters of the river, braving the enemy's dense artillery fire. Everyone knows that the river crossing that is about to begin is a fierce battle, a life-and-death battle in which guns and bullets rain and rapids kill a path for the Red Army.
The Red Regiment of the Red First Division of the Red Army, to which Li Decai belonged, received an order from its superiors to cover the advance detachment's forced crossing of the Dadu River on the banks of the Dadu River before the enemy's "encirclement and suppression" deployment was completed.
After the battle began, in the fierce gunfire, the advance team members boarded the ship and rushed to the opposite bank ferry.
Li Decai and the soldiers suppressed the swarming enemy, and for a time the sound of gunfire accompanied by the roar of cannons resounded over the entire Dadu River; Li Decai was even more brave in battle, striving to create favorable conditions for the advance team that crossed the river, and one person took turns to control two machine guns, fiercely suppressing the enemy's firepower, and covering the comrades who forcibly crossed the river.
The advance troops crossing the river successfully controlled the crossing on the other side of the Dadu River, and Li Decai successfully completed the task assigned by his superiors, allowing the follow-up troops to cross the river smoothly.
Li Decai's heroic performance made a contribution to the successful crossing of the Dadu River, and the regimental commander Yang Dezhi praised: Li Decai is our most powerful machine gunner, and it is no problem to have him crossing the river.
In 1958, the staff of Zhongnanhai warmly and politely received a dark-skinned, tall man in military uniform, who was None other than Li Decai.
Li Decai did not report in advance, so he told the guards that he wanted to see Chairman Mao, and the guards told him that he needed to obtain approval in advance to see him. I'm Li Decai. ”
After being blocked again by the guards, Li Decai realized that it was no longer the time for war, and the leaders of the country needed to report in advance.
The guards did not let in, Li Decai thought that he might run in vain, just when Li Decai was a little anxious, at a moment of no avail, approaching a little boy that Li Decai knew, when he was in Yan'an, he was in charge of logistics management work, and many family members were familiar with it, Li Decai recognized that the little boy was a leader's child, just this little boy also saw Li Decai, the little boy did not expect to see Uncle Li in Zhongnanhai, he was very happy.
Li Decai thought of a good idea, took out a piece of paper and wrote a short letter, in which Li Decai signed his nickname as a local guy and asked the little boy to bring it to the chairman.
The nickname of the local guy comes from a joke made by Li Decai himself, and this nickname has also been heard by the chairman.
The cause of the nickname was that once Li Decai was assigned a captured German-style military pants, Li Decai, who had never worn such high-end clothes, was confused and actually put the opening on the back, and also wore this military pants out of the door, was laughed at by everyone, Li Decai felt nothing, did not care about this, since then Li Decai's title of "tulk" has spread.
After Li Decai handed the letter to the little boy, he waited outside, and it was not long before the guard came out and said that he would take him to the chairman, and Li Decai happily followed the guard to the reception room.
Chairman Mao warmly received him, and Li Decai was also very excited to see that the chairman was still as cordial and easy-going as he had been in the past, and there was no shelf at all.
When Chairman Mao saw Li Decai and thought of the nickname of the tulao written by Li Decai on the letter, the chairman smiled and said: The tulao is coming, sit down!
Li Decai respectfully saluted the chairman and greeted the chairman, and Chairman Mao also quipped: Are you not wearing pants today?
The people around them were very surprised, and the chairman laughed and explained the origin of Li Decai's nickname, and the people present laughed after listening, and Li Decai also laughed.
Li Decai carefully reported his recent work to the chairman one by one, and later the chairman also helped Li Decai solve some difficulties in his work.
Li Decai had a wide range of friends, was bold, eclectic, had a very good popularity in the military, many chiefs were very familiar with him, and when they saw him, they would laugh and praise him; Li Decai later served as the commander of the Baoding Military Subdistrict, and he dedicated his life to the revolutionary cause and was a respectable revolutionary predecessor.
