Sun's career movement is vertical and horizontal.

1936, in the marathon of Berlin Olympic Games, a Korean athlete Sun stood out and won the championship in one fell swoop with a score of 2 hours, 29 minutes and 2 seconds. He became a national hero who won glory for the weak Korean nation during the Japanese colonial rule. However, according to literature and history research, Mr. Sun used to be a bank clerk. He not only won the gold medal in the marathon, but also excelled in banking.

On the 60th anniversary of the recovery, the First Bank still retains valuable information about its banking experience.

The first bank said that Sun's indissoluble bond with the bank was on April 1940+0. After graduating from Meiji University in Japan, he was employed by the Korea Savings Bank (now the First Bank).

At that time, if you want to enter an enviable bank, you must pass a complicated recruitment examination. It is said that Sun's production can be successfully hired, and the Korean Athletics Federation has played a vital role in recommending this Olympic gold medal hero.

Banks are not something that any idle person can do well. It is reported that Sun is not proficient in the abacus necessary for bank employees, so he works hard.

However, in the work of saving persuasion, he achieved four times the highest personal attraction performance before. So it is famous not only in Korea Savings Bank, but also in other banks. The bank reference room still holds the identity guarantee, resume card and resignation letter submitted by Sun when he joined the company.

However, his career as a bank clerk did not last long. After working for four years and three months, Sun submitted his resignation letter on the grounds of family status in July 1944 and returned to his hometown of Sinuiju in the north of Pyongyang. From then on, he really embarked on the road of hard sports.
