Online shop competition is fierce. There may be hundreds of businesses selling the same milk powder online. In the case of similar price, merchants can only increase the sales of Feirui milk powder by giving gifts. Feirui is an offline product of He Fei, which specializes in offline sales channels. It is mainly sold in some maternal and child physical stores online, and there are few milk powder activities in physical stores, all of which are completed through points.

He Feixing's extraordinary series products integrate global R&D resources to create a "consistently good milk powder" that is "adaptable" and truly suitable for China babies. Xingfeifan revolutionized the "upgrade" of important nutrients, and the formula was suitable for breastfeeding.
