Better be careful. The registered health care products holders of "Mermaid" trademark are Beijing Digital pioneer electronics Commercial Co., Ltd. and Shaanxi Tianfu Health Care Products Co., Ltd., but they have also applied for this trademark, but they have been rejected.

The applicant for diet pills is also an individual from Jilin.

At present, judging from the ownership of trademarks, neither of them should be associated enterprises of mermaid. As for diet pills, I don't know much, so it's hard to draw a conclusion.
