Jiang Taigong is one of the customs in the Han nationality where everything is forgiven. On New Year's Eve, the Kitchen God and couplets should be posted to take him home and keep him safe for one year. It is also necessary to post door gods, Spring Festival couplets, blessings, red envelopes and so on. Exorcise evil spirits and receive blessings. In the old society, it was forgivable for the Han people to even post Jiang Taigong here.
