This depends on your surname genealogy or family tree, which has been compiled. Otherwise, there would be no generation with the word "福".
Of course, if you really can’t find it, then you can make it up yourself and pass it down from generation to generation. Usually eight characters are enough. One generation is assumed to be 30 years (not age, it is assumed to be 30 years old) Give birth to a child), eight words can be used for 240 years. Let me help you design it:
1. Fu
2. Xiang
3. Harmony
4. Harmony
5. Cheng
6. Cai
7. Hua
8. Dragon
