Don't listen to these advertisements. What are the celebrity endorsements looking at? See the effect? I bet that Wang Gang had never heard of this brand before other manufacturers found him to advertise! I didn't know there was such an instrument made of principle. Endorsement, isn't it to see if the money is enough? Li Jindou also speaks for other people's big baths. You see, as long as you pay more, you can speak for the chicken. What's more, a health care instrument that doesn't know what is good but can be sure that it should not cause great harm?
