Why do people always say that Tianqi Dan is not good?

Because the price is too low, the quality cannot be guaranteed. The price of Tianqidan is about 1 1,000 yuan. Tianqidan can't provide normal quality assurance because of its low price, especially health care products, and can't get timely and effective after-sales service, and at the same time, it can't claim for the harm and influence caused to human body.
