The brand "Wanglaoji" was first leased to Jiaduobao by Guangzhou Pharmaceutical Group in 1990. Later, Wonglaoji became more and more popular as people bought it. In addition, after the Wenchuan earthquake in 2008, Wonglaoji donated 100 million yuan. It was even more favored by consumers, so Guangzhou Pharmaceutical Group became "jealous" and wanted to make money from the "Wang Lao Kat" brand, so the two companies had a dispute and the brand was withdrawn by Guangzhou Pharmaceutical.

"He Qi Zheng" It is the name of a herbal tea produced by another company, Fujian Daliyuan Group. It initially followed Wong Lao Kat’s marketing method, and it has developed well recently.
