On a business trip to Guangzhou, a female classmate who has been there for many years invited her to live in an empty house. How about saving money for a trip like this?

If it&;s Guangzhou, it&;s definitely polite. Cantonese people, especially Guangzhou people, generally don&;t invite friends and relatives to be their guests, but usually have banquets outside their homes. The most famous and frequent way is to drink tea, eat and be guests, so they don&;t invite them to live in their own homes.
