What are the famous relays in China? The more detailed the better (I said the brand), such as; Xiamen Hongfa.

Matsukawa and Hongfa made in China are better. Matsukawa Company is headquartered in Taiwan Province Province, and has two branches in China. The main markets are Europe, America and Southeast Asia. Hongfa has agents in Xiamen and all over the mainland. The biggest difference is that the raw materials of Matsukawa relay are imported from Japan, which is the same supplier as Omron, and Hongfa is the raw material of mainland China. The cleanliness level of Matsukawa workshop is millions, which is not available to other relay manufacturers in China. Generally speaking, Matsukawa's position is the international front, and Hongfa's position is the domestic front. China is still relatively good: Huigang, Asia Dragon, Sanyou, Le Song, Helishun and so on. But the main advantage of these manufacturers lies in the price. After all, there are still many compatriots in China who can't afford good goods.
