The produced VE must be fake, because I also bought a bottle, which made me dizzy. Now I bought the Yangshengtang in Hainan, and compared it, there is a big difference. Shanghai's shell is hard, dark in color, and tastes heavy when broken. Shells produced in Hainan are soft and brightly colored. It is true that buying VE from Hainan was entrusted to Hangzhou, Zhejiang.
