In china have 56 ethnic groups Each of them has their own cultures and customs, Majority Chinese people not follow any religion but tradition and rituals, in this 56 group only 7 ethnic group get funeral rights according to their customs, the rest all need cremate body after death. every ethnic group name mentioned on Chinese national Identity card. for example a foreigner Muslim or christian man married a Chinese lady and she belongs to Han or any other and her husband give her his religious name and dress also she starts follow his religious rituals and customs leading a religious life even if when she die the body will cremate according to her ethnic group which mentioned on her identity card. I have seen many Arabic man married Chinese girls and give her Muslim name also dress and teach them all his religious rituals also they have children. as I understand many of them not aware about the funeral law and rights in china. So while you follow religious life also you need care your spouse funeral rights also ..
