Which is more authentic, Ren Qing, Changdu Tibetan Medicine Factory or Xizang Autonomous Region Tibetan Medicine Factory? thank you

Anyone who knows Tibetan medicine knows that Renqing Changjue, a precious top Tibetan medicine, is produced by only two Tibetan pharmaceutical factories in China. There is a Tibetan pharmaceutical factory in Qinghai, and the other one is Manna Renqing Changjue produced by Xizang Autonomous Region Tibetan Pharmaceutical Factory. In order to protect this Tibetan cultural heritage, the state has only approved the production of two Tibetan pharmaceutical factories, which means calling on two manufacturers. However, some Tibetan pharmaceutical companies see that it is profitable, and they all produce Renqing Changjue and Seventy Flavor Pearl Pills, the two most famous Tibetan medicines. However, these two Tibetan medicines have a core patented technology "Zotai", which is not available in other Tibetan pharmaceutical factories. Without Zuo Tai, the effect of the product will be greatly reduced, just like a healthy person without limbs. These patented technologies are unique to Xizang Autonomous Region Tibetan Medicine Factory.
