Hunan Liu family tree and generation

My name is Liu Jinze, my ancestral home is Changde, Hunan, and I now live in Wangying Town, Lichuan, Hubei. Since the genealogy book has been lost for many years, I can only remember the previous generations; Because the computer has only recently been connected to the Internet, I looked up the Liu family tree and did not see the names of my family. In fact, the ancestors of my family were nine sons who entered Sichuan. There are thousands of people in Guanglichuan. Why are the Liu clan's clan leaders and clan members joined together? Will the statistics be finished/
