Liu Yun Rui's next foray into GL is an advert, released in 2021, for the Chinese makeup brand Florasis, starring Qi Xiaxia (圻夏夏) and Jiu Jingyan (九井宴). It begins in the present day, with two women walking past each other. Their eyes meet, and it triggers a flashback of them being lovers in a past life long ago. One of the women drops her Florasis lipstick, and the other picks it up and hands it back to her. This went briefly viral in international fandom spaces, so if you see references in the wild to 'THAT Chinese sapphic lipstick reincarnation ad', this is almost certainly what they're talking about.
