In 1948 the Chinese national team reappointed Lee as coach, this time for the Football at the 1948 Summer Olympics. On a self-financed training course in the Philippines and Thailand he took the team away for three months while they prepared for the London Olympics. At the tournament China faced Turkey in the last 16 but were defeated 4-0 within the game. After the defeat Lee returned to China in the middle of the Chinese Civil War and did not coach until after the conflict. By then his team had been split into two, Republic of China national football team (later renamed Chinese Taipei) and China national football team (registered as PRC in FIFA). In 1954 Lee decided to join the Republic of China national football team as their first permanent coach and lead them to win the 1954 Asian Games. He would continue to coach the team at the Football at the 1958 Asian Games where he guided the team to win the tournament once more by beating South Korea 3–2 in the final.
