The effect is different. The products of Shanghai Yangshengtang have been sealed up by the Administration for Industry and Commerce and the Food and Drug Administration in many areas. Shanghai Yangshengtang, which I just bought, has a stomachache. Now I'm eating from Hainan Yangshengtang. Although it is more expensive than him, it is only 150 a year, and the content is higher than him. It's safer, and now you can't buy cheap fakes.
