[AshleyAnn]

S stands for provincial highway, while G represents national highway. Related Introduction: 1. Overview: In China, road numbering rules are primarily categorized into three levels based on their administrative hierarchy: national highways (including national trunk highways), provincial highways, and county roads. The initial letters of the Chinese words for 'national,' 'provincial,' and 'county'—G, S, and X—serve as their respective identifiers, combined with numbers to form the numbering system. A highway route number consists of a one-letter administrative level code followed by three digits. 2. Differences: On road signs, those with a red background indicate national highways, while those with a yellow background signify provincial highways. National highways are major arterial roads with national political and economic significance, connecting large and medium-sized cities across the country and forming the backbone of the national highway network. The numbering of national highways begins with the letter G.
