To tell the truth, the Korean diet pills I bought during my trip last year were useless, which scared me to change them quickly. Now it's Lei Guier, who loses weight quickly and well without side effects. Sometimes it's really not foreign or good, especially Korean goods. It really feels like everyone is blowing it. Last time I saw the news, it was said that Korean duty-free shops specifically targeted at fakes from China tourists. What a shame. I don't want to travel to Korea anymore.
