You can drink it with confidence. The water you buy may be produced by the old production line that the farmer bought when he built the factory in the early days. This line is more than 10 years old, and the bottle caps and bottles are engraved. It's Yangshengtang, because it is a company affiliated with Yangshengtang. In the past, production lines like this used paper labels, but now they use plastic labels to save costs. The soup does not need to be changed, and the water is still the farmer's water.
