National highways, compared with provincial highways, county roads and rural roads, national highways generally need to meet the standards of highways above the second level (high-speed, first-class, second-class), but can also be third-level or even fourth-level highways.
At present, China's national highways mainly include:

Why are there no National Highways 226 and 313?
Both of these originally existed, but were later withdrawn. National Highway 226 (or "National Highway 226" or "G226") starts in Chuxiong, Yunnan and ends at the National Highway in Mojiang, Yunnan, with a total distance of 288 kilometers.
National Highway 313 (or "National Highway 313" or "G313") starts in Anxi, Gansu, and ends at Ruoqiang National Highway in Xinjiang, with a total distance of 821 kilometers. Partially abandoned and relegated due to desert erosion and a small population. The former G313 section of Guazhou County-Dunhuang City is the First Class Highway of Anton, Gansu Province; the Dunhuang City-Aksai Kazakh Autonomous County section is the G215 line; the fork road junction of Aksai County Daoban-Annanba Village is gansu S313 Line; and the Annanba Village-Ruoqiang County of Xinjiang is now abandoned.
