After using Huayang's products for so many years, I think I have the following advantages. Our manufacturers are technically capable of R&D, so we have done a good job in product upgrading and innovation. The technical service strength comes from the front line and the experience is also very rich. What is more important is the concept of health preservation, which advocates internal health preservation and external health preservation. It is not to kill insects when you come up, but to fight diseases when you come up, and to advocate fish farming first, which is different from other manufacturers.
