Bulls and cows. What stem?

A girl gives you Niu Niu, which means that this girl is interested in you and wants to fall in love with you. Didn't the Internet say that Niu Niu is rich in oil some time ago? There are two cows on the eastern hillside. The bull said to the cow, I love you, the cow said to the bull that you are ashamed, and the bull said that you are not ashamed, and I love you.
