In the traditional custom of China, friends and relatives are invited to celebrate the completion of the new house, which is called "dinner party". The purpose of eating the admission meal is to celebrate the completion of the new house, and also to pray for auspiciousness, unity and harmony. When eating New Year's Eve, the host will warmly entertain relatives and friends, and everyone will also send blessings and red envelopes to express their blessings and best wishes for the new house. Eating an invitation meal can not only enhance the affection between relatives and friends, but also show the hospitality of the host.
