Do you agree Malay or Muslim daughter in law broke heart of non muslim's in law?

[teyo]

Sad! Because!

1. In my country the children follow ways of Muslim life from mother and her parents.
2. The children do not know how to respect parents of father's family, culture and tradition.
3. The children acknowledge themselves as mother's family race;
e.g. if mother is Malay than they will say they are Malay ignore about father race

BUT! If father is Chinese or Indian

... according to Chinese or Indian culture the son has to carry family name and generation

... where is filial piety of Muslim's wife !

I wonder do they refuse to understand or do not wish to understand the in law's tradition or culture.

Or do Allah! Islam! followers should not follow the tradition or culture of non Muslim family?

This is Islam teaching that Nabi got from God?
