How to treat Yili and Mengniu?

I think Mengniu's pure milk is sweeter than Yili, but Yili is thicker than Mengniu. In TV commercials, I can be sure that Yili advertised for a new product, and Mengniu soon advertised for a similar new product. About 2008, Yili's new product "Yili QQ Star" was born, and a year later, there was "Mengniu Future Star". Earlier, Yili produced "Yili Yogurt", and Mengniu had "Mengniu Yogurt" to compete with it. In terms of ice cream, Yili's "Yili Mood", "Yili Popsicle", "Yili Tricolor Ice Cream" and Mengniu have corresponding "Green Mood", "Mengniu Popsicle" and "Mengniu Tricolor Ice Cream" respectively, and the sales of the two are equal, so it is unclear who imitates who first. With the pursuit of high-end dairy products, Yili took the lead in creating "Jin Dian Organic Milk". After a period of time (personally, it is quite long), Mengniu has "Telunsu", which seems to sell better than Jindian, and it is one of the few successful examples of Mengniu imitating Yili. With the running man's fire, "Elaine muxi" is well known, and "Mengniu Innocence" has gradually entered the public's field of vision. But Anmuxi seems to have developed better than Chunzhen, at least in the number and taste of advertisements, these superficial things are better than Chunzhen. Personally, I think Mengniu is imitating Yili most of the time, and the first hot comment can also confirm this conjecture.
