Because Jiaduobao and Wang Laoji are the same formula, at first GPHL only rented the "Wang Laoji" trademark to Jiaduobao instead of selling it. However, GPHL saw that Wang Laoji was selling well and asked for an increase in rent. Later, Jiaduobao disagreed. GPHL sued Jiaduobao for infringement and used their Wang Laoji trademark, which was later renamed Jiaduobao. The two formulas were the same. Later, Wang Laoji said that Jiaduobao used their red appearance and said that it was infringing. Finally, there was a gold jar of Jiaduobao.

Also, Jiaduobao's bottle is lighter than Wang Laoji's, and Wang Laoji's bottle is still heavy after drinking.
