Zhang Ziyi and Rosamund Kwan.

Isn't your view quite correct? This is exactly what you said.

Rosamund Kwan was born in 1962, younger than Zhang Ziyi's 1979 17 years old. She can be her mother.

Zhang Ziyi was famous for playing Zhang Yimou's My Mom and Dad in 1999. At that time, Rosamund Kwan's image of "Thirteen Aunt" in Huang Feihong series films was deeply rooted in people's hearts.

Now Rosamund Kwan has almost faded out. Oh, in 2005, she and Wallace Huo filmed "Pat the Head" together, and then it seems that she can only be seen in advertisements.

Now, Zhang Ziyi is in full swing. Isn't it also on the Spring Festival Gala?

Conclusion: What you said is right, and the person who is arguing with you is wrong ~ ~ _
