In fact, the ownership of the Wanglaoji brand and formula belongs to Guangzhou Wanglaoji Pharmaceutical Co., Ltd. (referred to as Guangzhou Pharmaceutical, a state-owned enterprise).

Hong Kong Hongdao Group only rented the trademark and formula of "Wanglaoji" and established Jiaduobao Group in mainland China (first in Chang'an Town, Dongguan) to operate the production and sales of red cans of Wonglaoji. Tetra Pak (green box) is still produced and sold by Guangzhou Pharmaceutical.

Generally speaking, the trademarks and formulas are state-owned, even in Hong Kong, they belong to China, so Wong Lo Kat is our own brand.
