Emperor Taizong wanted to marry his daughter to a courtier, who was the best housekeeper in North Korea. Fang Fang has two sons, the first son's house is intact, and the second son's house is intact, so the house where he married the second son is intact.
According to unofficial history's records, the family was clumsy and could not get Levin's love. Later, when he met the debating machine, Levin fell in love with it. The debating machine is the apprentice of Master Xuanzang, and the famous "The Tale of the Western Regions of Datang" in history was written orally by Master Xuanzang.
Later, Levin and the debating machine were exposed and the debating machine was beheaded. Master Xuanzang could do nothing about it and regretted his disciples.
