The shirt says 天滅中共 or tiān miè Zhōng Gòng (Heaven destroy the CCP). I looked the phrase up online as I hadn't heard it before, and no surprise, these shirts are available from the Epoch Times -- who, as the propaganda wing of Falun Gong, has been extremely supportive of the Trump administration, mostly because he's anti-China (and therefore the CCP?). The panda head must then be some kind of weak commentary on China, but who has any idea what it could be.
