Blue Sky with a White Sun
In 2015, a pro-independence activist, Denis Chen, designed the Taiwan Passport Sticker (Republic of Taiwan sticker) to be placed on the front cover of ROC passports. The stickers re-brand the country's name as 「臺灣國」 (literally, "State of Taiwan") and "Republic of Taiwan" , as well as replacing the existing national emblem of a Blue Sky with a White Sun with cartoons of either Jade Mountain, Formosan black bear, or pro-democracy activist Cheng Nan-jung.
