My grandfather
This is my Waigong, my mom's dad. The chinese are crazy about what you call your relatives. Your aunt on your dad's side isn't called the same thing as an aunt on your mom's side. Then it's different for relatives married into the family. It's so confusing! One time I called my aunt-in-law (if you're lost stop reading. it's really not worth finishing) what you would call your mother's sister and everybody laughed...i died a little inside :0)
