Flags of the ROC, PRC, and U.S. can be seen flying atop adjacent buildings in San Francisco Chinatown. Most benevolent associations in San Francisco, including the Chinese Six Companies, continue to fly the ROC flag due to their close relations with the KMT.
In vexillography, the canton is a rectangular emblem placed at the top left of a flag, usually occupying up to a quarter of a flag's area. The canton of a flag may be a flag in its own right. For instance, British ensigns have the Union Jack as their canton, as do their derivatives such as the national flags of Australia and New Zealand.
