Traffic can be divided into local traffic, provincial traffic and domestic traffic. Locally, the priority is local traffic >; Intra-provincial flow > domestic flow; In the province but not in the local area, the local traffic is impassable, giving priority to the use of provincial traffic; At home but outside the province, only domestic traffic can be used.

Local traffic: supports local traffic (where the number belongs).

Intra-province traffic: supports the traffic used in the province where the number belongs.

Domestic traffic: support national traffic (except Hong Kong, Macao and Taiwan).
