Lee Chang-ho was born on July 29, 1975 in Jeonju, South Korea, the second son of Lee Jae-yong and Choi Shou-hee, the "Lee Watch Shop" in Chung-dong (Note: "Dong" is equivalent to a neighborhood). According to Lee Chang-ho's mother, when she was pregnant, she once dreamed of a giant python in the pot. The python represents wealth and good fortune in the meaning, and Lee Chang-ho's younger brother Lee Young-ho believes that the python in the east means a dragon, and the python can transform into a dragon.
As a child, Lee Chang-ho was known for his quick calculations, competitive spirit, thoughtfulness, and stubborn personality. When Lee Chang-ho was in elementary school, his IQ test reached 139, Chang Hao in China was 138, and Luo Xiehe was 160. If you simply look at the IQ, you can't see the advantages of Lee Chang-ho. But IQ can be used as an important reference, not absolute. Einstein's IQ was not the highest among humans, and the highest known human IQ was William James Sids, between 250 and 300, but he did not make any outstanding achievements.
Lee's success consists of at least three factors:
1. Talented in Go
2. Persistent and single-minded personality
3. The world's first teacher, Cao Xuanxuan
Lee Chang-ho has won a total of 138 titles in his career, including 17 world championships. By contrast, Japanese title number holder Cho Ji-hoon won his 75th title in 2019 at the age of 63, but Lee Chang-ho's master "Emperor of Go" Cho Hyun-hyun has already won 157 titles in 2003 at the age of 50, including nine world titles, setting a Guinness World Record. Chinese head coach Yu Bin insisted that Cao Li's master-apprentice team has improved the overall level of Korean Go by a large margin, and it is precisely in the long-term grind of Chinese Go that it surpassed Japanese Go.

Lee Chang-ho's Three Kingdoms Go Tournament results are even more cool, including 19 wins and 3 losses in the Nongshim Cup, 8 endings, and the main player will win 14 consecutive victories across the session, such results, no one in the world chess world can compare.

Lee Chang-ho crushed the contemporary Go leaders of Chinese and Japanese Go by a big score: Ma Xiaochun, Chang Hao, and Zhao Zhixun. Convincingly ushered in an undisputed "Lee Chang-ho era". Before that was Master Wu Qingyuan, who also created a "Wu Qingyuan Era" that could make the world first. Master Wu Qingyuan is known as the "Showa Chess Sage", and Lee Chang-ho is known as the "Stone Buddha".
After the alpha dog was born, it became the undisputed "God of Go", and the moves it recommended became the most authoritative moves. More importantly, there is a quantifiable comparison of data, which is the degree of coincidence. Under the same rules, the higher the coincidence between the chess player and the AI recommendation, the higher the level of the chess player, which is very scientific. With the degree of coincidence, Guan Gong can also fight Qin Qiong, and the most famous top masters in the history of human Go can be compared with each other.
As can be seen from the following figure, after the emergence of AI, the overall level of human Go has increased rapidly.
Cui Can's five-paragraph essay "Celebrity" or "Industry 5"? From the "Go AI analysis" to see the level of Chinese Qing Dynasty Go" can be described as a stone breaking!
Cui Can's five paragraphs in the paper came to the following conclusions:
Lee Sedol and Gu Li led the list, and the average coincidence value of the two was about 2% higher than the average of all chess players. However, the data of these two players is not the highest among all chess players, and the average coincidence of Ke Jie's World Series finals has reached 57.08%. Since its chess score (more than 180 hands) was only 9 innings, it could not be included in the chart.
Surprisingly, Lee Chang-ho's rating ranks last. This is not the final "nine consecutive ya" of his World Series career that pulled down the AI evaluation of Go - remove this part of the data, and the average degree of coincidence has not changed. From the side, the "credibility" of the degree of coincidence is reflected.
As for why the contemporary recognized king of chess is not highly evaluated in The Go AI, there are the following possibilities: First, the Go AI is not waiting to see Lee Chang-ho's "slow" style, and many moves have been rated as "slow hands" and do not match. Second, Lee Chang-ho's brilliant record stained the light of the times, and at his peak (1995-2005), the overall level of other chess players was weaker. The average coincidence of World Series players during this period was 52.07%, which is almost equal to the value of the "1988-2000" group in Figure 14. From this point of view, Cao Xuanxuan can be described as a position ahead of the times. Third, the sample only counted the data of the first 180 hands, resulting in The inability to exert Li Changhao's "official divine skills".
Is Lee Chang-ho's achievement really a "peer foil"? I think lee chang-ho's strength is beyond doubt, Lee Chang-ho and Lee Sedol played a total of 75 sets from 1999 to 2018, Lee Chang-ho led 39:36, and Fanqi led 7:3. Even at the peak of Lee Sedol, Lee Chang-ho and his battle results were mutually successful. Lee Sedol also has great respect for Lee Chang-ho, calling him the "God of Go" in his eyes before the emergence of AI.

I think Lee Chang-ho is a giant python dragon in the world chess world, do you agree?
