How did the partners in cross talk decide?

Free choice, the actor thinks that another actor is suitable to partner with him, so he puts forward his own ideas to Degang Guo or other leaders of Deyun Society, and they will make arrangements when they think it is appropriate. For example, the combination of Zhang Yunlei and Yang Jiulang was originally thought by Zhang Yunlei that Yang Jiulang was very suitable for him, so he put forward ideas with Degang Guo and Yu Qian, including Yang Jiulang himself, and finally contributed to the now popular "Nine Braids" combination of Deyun Society.
