Stan Liou (M67) said that my earlier post on Chinese Names is only partially correct.
I wrote that Chinese siblings share the first part and second part of their names and vary only in the third part.

Stan said that siblings (mostly from the Northern Part of China) share the first part and third part of their names and vary only in the second part.
