People who buy property (房产) or move into a new apartment or house usually hold a housewarming party. The party is an opportunity for friends and family to congratulate (祝贺) this person on their new home. It is a tradition (传统) to bring a gift to a housewarming party. Decorations (装饰品) for the new house, such as pieces of art or potted plants, are good housewarming gifts. You can also bring food or drinks to share with the other guests. The host or hostess of the party will give all the guests a tour of their new home. Sometimes, because housewarming parties usually happen shortly after a person moves into their new home, guests may be asked to help unpack boxes. This isn’t common, though.
