It can be basically judged that the authenticity is questionable. First of all, if it is set as authentic, then whether it is a manufacturer or a distributor, if it sells the product at a price 80% lower than the market retail price, it is suspected of using unfair means to compete and disrupting the normal market order. Suspected of dumping, so regular brands will not commit illegal acts just for a live broadcast.

Secondly, it does not conform to normal business logic. The most fundamental purpose of merchants producing and selling goods is to make a profit. Even if they choose to make concessions for publicity, they will only give up profits and will not reduce costs.
