Zhang Sanfeng and Guo Xiang are three years apart. Why are they contemporaries of the exterminator and the abbot of Shaolin Kong Wen?

Zhang Sanfeng and Guo Xiang's parents should be about the same age, but the marriage time is different from the birth time of their children. As for the same seniority as the abbot of Kong Wen, there is no difference: people used to have rules on their names, or they were younger than Kong Wen and had normal seniority. In ancient times, as long as a person was skilled in martial arts and enterprising, and respected the teacher, the most important thing was that Master died early! You can be the boss. They are all leaders of big sects. Of course they are the same.
