Panshan's water brands are very mixed, and the quality of barrels is not very good. Deyiyuan is a brand in Beijing. It was originally bottled water for the Great Hall of the People, and the quality was good. All the people walking in Beijing are high-end customers. It seems that I just entered Tianjin in May. But it is said that many government agencies are useful. I've tasted their water test, and it's really delicious. I don't know what mass production will be like. I hope I can help you. Ha ha.
