Do you want to buy it? If both manufacturers can't buy it, they can only buy it at the dealer. Kang is made in China and the manufacturer is in Nansha, Guangzhou. Xilaijian is a foreign-funded enterprise, a Korean manufacturer and several factories in China. But the price is more expensive than the former. See if you want domestic products or foreign products. If you want it, come and buy it from me. I have both.
