  Liverys of different bus companies differ. The most ordinary livery is often called "SH Livery", which was established in 2001. Bashi Group buses, Jinshan Bus Co. of Jinshan District, Minhang Bus Co. of Minhang District and other private bus companies use such kind of livery, while different in colors.
context_section_description: Most downtown buses use numbers to specify the lines, while suburban buses and a few downtown bus lines use Chinese characters. In the recent decade, there has been increased activity in network optimization and as a result, many bus lines have been cut, shorted, and combined. Many named bus lines have been converted to number lines with a flat fare. Some regular lines have been changed to rush-hour only, while still keeping their original line numbers.
