single or double-digit cars are 1 yuan-made cars, which are the best service lines in Wuhan. For example, No.5 and No.42

7XX belong to the Tramway Company, and 8XX originally belonged to Hong Kong Tongheng Company, and later they were merged into the unified management of Wuhan public transport.

there are also cars in far-off cities and cars with trapezoidal charges, such as 222, 292, 757, 758 and so on.

There are also tourist routes in Wuhan, such as 412, 411 and 64.

there's nothing about the rules, just remember a few routes, and then look for a bus when traveling. For unfamiliar places, and you can't find a bus directly, then find the bus in the area you want to go to, and then transfer there.

For example, there is no direct bus from Qilin Road in Hanyang to Wangjiadun Station in Xudong Street, so you can find a bus in Wuchang District or Qingshan District, and you will find that there are 617 buses that can go to Yujiatou and 537 buses that can go to Dongting, so you can choose to take Wuchang and transfer to 541 to get to your destination.

I hope my answer just now can help you.
