Remember the movie In the Mood for Love (《花样年华》) when Tony Leung reveals his love secret to a hole in a tree? Well, as a fan of the movie, Li Wenqi, 20, also talks into a tree hole to share her confusion and secrets, and “seek comfort and inner peace”. The only difference is that the Shenzhen University English major’s tree hole is really a smartphone app monitored by a professor in Wuhan (see profile) who answers students’ questions and gives them advice.
