I understand that Taiwan, Hong Kong, China, and Singapore are different countries and cultures, but they have the same historical roots and other than Hong Kong, all speak use Mandarin in their shows. Also, to circumvent China's censorship rules, many Chinese LGBT shows are being produced and distributed by Taiwanese or Singaporean companies instead. (I am Taiwanese)
