When it comes to choosing infant formula, many families consider this a major challenge. This is because most parents don't know how to choose the right formula and won't bother to read the instructions. Jinlingguan (a brand) is even less likely to be understood in terms of its composition and value. Most people are still influenced by herd mentality: if relatives or friends buy a certain product, they follow suit without much thought.
Even under the influence of this herd mentality, most people seem not to make mistakes. We could say that the eyes of the masses are sharp. I recently looked up a 2011 ranking of infant formulas. I'm not sure how accurate this list is, but the top four spots were all occupied by foreign brands. Yili was the only domestic brand to make it into the top five, which was quite an achievement.
This ranking may be a comprehensive one, considering factors other than sales volume, such as quality, which might also be an important indicator. I also checked some other rankings, unsure which one is more authoritative, but they are all pretty similar. For example, Yili consistently ranks high due to its excellent product quality and affordable price suitable for the general public. It appears that the eyes of consumers are indeed sharp, and good products will eventually be discovered by them.
