Who is the character in this poster of Long Er?

I thought someone would answer later, but I didn't answer. No one has finished it yet. Let me come here. Is this a dead dragon (just kidding)? (I thought it was good in the early stage of Dragon II comics. Not many people have seen it before. )

From left to right are Chu Zihang, Ricardo M. Lu, Xia Mi, and Chu Tianjiao (Chu Zihang's father before he was named).

By the way, Shami should be a beginner. There is no double ponytail in this cartoon, only this image is in the previous poster)

I leafed through the magazines piled up at home. Chu Zihang's father took a random clip without introducing him.
