The green carton of Wong Lo Kat previously seen on the market was produced by Guangzhou Pharmaceutical Group, while the red tin can of Wong Lo Kat was produced by Jiaduobao Company. The Wonglaoji trademark was registered by Guangzhou Pharmaceutical Group and Jiaduobao Company. Signed a trademark lease contract with Guangzhou Pharmaceutical Group until 2010. The former GPHL executives signed a supplementary agreement with Jiaduobao Group, extending it to 2020. However, it was later discovered that it had been signed under bribery conditions, so the supplementary agreement was deemed invalid. Jiaduobao Group eventually lost the right to continue to use the "Wanglaoji" trademark. Therefore, the original red tin cans on the market are being overused. They have changed from having "Wang Lao Kat" written on both sides to "Wang Lao Kat" on one side and "Jiaduobao" on the other. In the future, the remaining words "Wang Lao Kat" will definitely also be be removed. Recently, the TV advertising slogan of Jiaduobao herbal tea has been changed from "If you are afraid of getting angry, drink Wanglaoji" to "If you are afraid of getting angry, drink authentic herbal tea." The Wong Lo Kat we will see in the future will be produced by GPHL. In fact, Wong Lao Kat’s fame was brought about by the operation of Jiaduobao Group, and it donated 100 million yuan during the Wenchuan earthquake, which left a good impression on the Chinese people
