Customs vary from place to place. We have the saying of "warming the pot" here, which is also called "burning the kang". The earliest reason should be related to burning the first fire after moving. Now "warming the pot" means inviting relatives and friends to have dinner at home after moving. Generally, there are four kinds of gifts: fish (meaning "more than enough"), meat (always sacrificing cold pork), vegetables (meaning "rich") and cakes.
