Composition of affiliated hospital

There are three people in my family, Dad. Mom, of course the other one is me. The three of us have three different animal signs.

Dad is a dragon. He is like an emperor in a dragon robe. He doesn't do housework at all. Of course, he has a lot of things. He is a university teacher and a company manager.

Mom is a sheep, but I think she is not gentle and strict with me.

Finally, I am a pig. I always bury my mother because I was born in the year of the pig. I hate pigs! Stupid and lazy, but everyone says I'm a smart pig, which makes me very happy.
