The difference between direct bus and ordinary bus.

Ordinary means that every time you pass a small county or city, you stop and get off to attract customers, that is, stop and go!

A direct flight means a direct flight to the terminal, which is faster if you can't get on or off passengers.

Distinguish:

Direct buses are generally air-conditioned, relatively large, generally direct, comfortable and fast, in good condition, high safety and high fares, especially for the business-oriented Eurostar.

An ordinary bus is an ordinary bus, which should include a sleeper and a minibus. If passengers wave to get on the bus halfway, they will also stop for class, which takes a long time and the car condition changes greatly. Generally speaking, the fare is cheaper than the direct bus. But regular buses are not necessarily black cars, and regular buses also have operating licenses.
