Li Ching-yu, center, wife of Taiwanese pro-democracy activist Li Ming-che detained in China, stands after she was denied boarding the flight to Beijing at the airport counter at Taoyuan international airport in Taoyuan, Taiwan, Monday, April 10, 2017. Li Ching-yu told reporters that airline staff told her Beijing authorities had canceled her Chinese-issued travel permit when she tried to check in on Monday. Li had hoped to fly to China to demand information about her husband who has not been heard from since March 19. The sign in Chinese says “Release/free Li Ming-che.” (AP/RSS Photo/Johnson Lai)
