My friend gave me a bike, NAKXUS9500. What brand is 26m02 1? What's the quality and price? thank you

The brand is the mountain bike of Naxas Naxadas. Twenty-six inches, the last twenty refers to twenty-one speed. The price is about 7800 to 1000, depending on how much the seller earns. This is made in Guangzhou, China. Said it was a mountain bike ... Let's go flat. The quality is average.
