Sorry, I wrote it smoothly, and made a low-level mistake about the title.
If Padmé and Xie Tiehammer are of the same generation, it's okay to call him Uncle Xie Zhi, because Uncle Xie can have two meanings, the grandfather of Xingyi, or the elder brother of the uncle.
But the first grandpa, the fourth grandpa, etc. in the back row are inferior, representing uncles and peers.
So it has been changed, and it is still called uncle, but Steve is called fourth master.
