Let's change it to "left".
Zuo Li, or Li Zuoyi, Li Zuozhi.
Because the word "Li" itself carries the word "Zi", there is no need to add "Zi".
Moreover, "Left" itself means assistance, and people assisted by capable people have a position that cannot be underestimated, so it is best not to follow the word "Left" or a pronoun noun. Zuo Yi means that he will only assist one person, which shows that he is simple and loyal; Help is to help the person you want to help in your heart.
