The future is like your own kind! Hengrui's product line is richer, so is Hausen (Hausen started his career on Hengrui's shoulders). It seems that the weather is good and the policy is good. Kangyuan products are relatively simple, in short, my impression of Kangyuan is the worst. I have done it in several big cities and hospitals, and I have never seen Kangyuan's peers and products!
