The specific method to be used and who to complain to depends on the situation.

1. If the milk tea shop’s production materials are expired or have three-no products, you can complain to the Market Supervision and Administration Bureau.

2. If the service attitude of the store clerk is not good, you can complain to the store owner. The franchise store chain brand can also complain to the headquarters of the brand.

3. If milk tea causes harm to someone, such as serious infringement causing personal injury, you can file a civil lawsuit in court in accordance with the law.

4. If a milk tea shop infringes on other people’s brands and trademark rights, the infringed party can report it to the trademark management department or the industrial and commercial management department and require the infringer to compensate for losses.
