To see whether a product is good or not, I personally summarized the following points:
1. Look at the main ingredients and sources of the products, such as bird's nest. If it is from Malaysia, it will be quite good. The bird's nest in Malaysia is well known.
2. Look at the size of the company. A large company means that the development is good, and the more popular the products are, the more they will develop and grow.
3. Whether it is independent research and development, independent research and development, or joining hands with the team, it shows its strength;
4. The ability to provide new products every year and inject new vitality into the market. .......
