Should I say I am Thai also?

Random thought. My mom is from the Philippines and my father is from Thailand. Although he and his siblings was born and raised there, his parents (my grandparents) are from China.

They speak Thai, their culture is Thai, but I mean there are still some traces of Chinese culture such as celebrating the Chinese New Year and speaking Chinese to his mom. But other than that everyone on my dad’s side of the family is from Thailand.

I’m not really Thai by blood, but then again many many Thais are Chinese by blood and not really native.
