探望

The train was about to enter the station, and he peeked out the window from time to time.

I saw a man looking around, not knowing who to look for.

He poked his head into the classroom and left without speaking.

This time I came to Beijing, I wanted to visit my old friends.

I am going back to China to visit my parents this Spring Festival.

I went to Shanghai on a business trip and visited an old classmate by the way.
