Kapok Flag

The Kapok Flag is the flag used by the Cantonese nationalist movement and represents the Cantonese people of southern China, as well as their language and culture. As one of the "nine independence" flags, it was banned in Hong Kong after the implementation of Hong Kong national security law.

Design and symbolism
The flag consists of three horizontal stripes of green, light brown and blue with a stylized image of a kapok flower in the center, the official flower of Guangzhou and a long-time symbol of Cantonese culture. According to its original creator, the green color represents freedom, peace and vitality; light brown represents the indigenous Nam-Yuet people, the ancestors and the origin of modern Cantonese people; and blue represents democracy and the ocean.

History and Usage
The first appearance of the flag on the Internet is no later than March 2010. Since its conception, it can be seen on multiple overseas protests against the CCP.
