What type of adult children could be regarded as filial in China?

You’re welcome.

Thanks for your reply.

The answers to the question could fall into three categories: make sure that one’s elderly parents’ material needs are met and that they receive medical treatment as needed, do one’s best to make them happy and to relieve their worries, and give them decent burials and funerals. Filial piety is associated with ensuring not only the physical comfort but also the emotional well-being of parents, including keeping personal and family worries private, so as not to burden them, and giving them funerals and burials to honour them after death.
