古 (gǔ): โบราณ

Teacher Gu has been teaching us history for ten years; his lectures are very lively.

Yesterday I ran into Gu Ming at the library; he was preparing for the HSK exam.

Dr. Gu, may I ask if I need to take medicine for my cold?

The braised pork that Chef Gu makes is especially delicious; our whole family loves it.

Manager Gu, I have already sent this report to your email; please check it.
