Which is better, North Bus or Yutong Bus?

Yutong is better. He has his own product research and development team. Now many technologies are very advanced. Now everything in the north is made in China, and the configuration and price are similar to Yutong's. How many accessories are difficult to buy and have poor after-sales? We bought two sets here the year before last, and the glass glue completely cracked less than half a year after we came back, with many problems. It's better for me to drive Yutong.
