Du Yueting (R), 42, kisses Zhang Tongyu, 35, a goodbye outside their restaurant, in New Taipei City, Taiwan November 20, 2018. It was a long debate between Du and Zhang over whether to paint rainbow colours on the walls of their restaurant. "I was really concerned about it...The public display of our sexual orientation can be quite controversial and I was worried that it might hurt our business," said Zhang. The couple, eventually, decided to go ahead. "We will serve those who are willing to come in our restaurant. For those who won't, we have no regrets for losing them," said Du.
