Many fans feel that the Taishan team invited Cui Kangxi to find a treasure last season. Since Choi Kang-hee has a good record under the leadership of the Taishan team, he has a lot of power in the club. The top management of the Taishan team not only gave Choi Kang-hee the right to recruit players, but also asked him to form a coaching staff according to his own needs. In this case, Choi Kang-hee recruited a strong South Korean player to join the coaching staff of the Taishan team. 
This strong supporter of South Korea is Choi De-joo, a descendant of Choi Kang-hee. Choi Deok-joo is a very capable head coach who once assisted Choi Kang-hee. At that time, when Choi Kang-hee was coaching the South Korean team, Choi Deok-joo served as an assistant coach. It is worth mentioning that Choi Deok-ju was also a brain-good midfielder when he was a player, and he played in the J-League for many years. The arrival of Choi Deok-joo has given Choi Kang-hee a boost and led the team to leapfrog in the AFC Champions League and league. 
Previously, Taishan's new center forward Zeka missed the AFC Champions League and the Chinese Super League due to a serious injury. Many fans are not optimistic about Choi Kang-hee's prospects for leading the team in the new season. In the eyes of some Shandong fans, if Cui Kangxi's skills and tactics are out of touch, he will not be able to play a high striker. Therefore, Zeka's injury did greatly affect Choi Kang-hee's skills and tactics. However, with the help of assistant coach Choi Deok-joo, Choi Kang-hee adjusted his tactics in time. 
The Tarzans can now win without a high striker, and they always have the upper hand on the field. In addition, when the Taishan team needed a center to launch a general attack, Choi Kang-hee moved Judson from the center back position to the center forward position, which worked very well. To sum up, the Taishan team invited Choi Dezhu as an assistant coach at the suggestion of Choi Kang-hee, which was also immediate.
