Brands that are relatively good are generally those that advertise or have completed a lot of projects, and are relatively well-known.
For example: Huangming, Linuo, Sangle, Tsinghua Sunshine, Hongli, Four Seasons Music, Taiyangyu, etc.
The one with a relatively advantageous price is Hongli which has the best quality/price ratio.
I didn't ask the poster if he wanted to buy it himself or if he wanted to become an agent, it's better to contact those manufacturers. If possible, go to them. manufacturers need to take a look.
