My Father, Wen Tianxiang, Won the Battle of Yashan at the Beginning

When Wen Tao regained consciousness, he discovered that he had traveled to the first year of Xiangxing in the Southern Song Dynasty (1278) and became Wen Tianxiang's eldest son, Wen Daosheng. There were only two days left before Wen Tianxiang was defeated and captured, and only three months left before the Battle of Yashan. There will be no China after Yashan. This is nonsense. China has always been there, but it has just changed its clothes. However, Wen Tao felt that as a Han Chinese, we should still strive to preserve the Han family's clothes. It's extremely difficult to make a comeback at this time. But since I have traveled through time, I have to give it a try. What if it works?
