Why didn't Zhang Daole go back to China to see his mother?

Because I became a fool! Do you have no memory of my childhood? I think my hometown as a child, I remember it very clearly! Even if he doesn't remember, do you think his father won't tell me about his hometown? How strong is the traditional concept of Shanxi people? Look at Peijie Village, Imperial City Xiangfu, Yu Chenglong and so on. How heavy is hometown? He knows nothing about it.
