Tāngdì Miào, a 600-year-old Taoist temple, is Guōyù's oldest building. Make sure to climb up to the stage, where there are two very rare Cultural Revolution–era paintings adorned with slogans exhorting the locals to work harder (the temple was a government building during that time). It’s also worth looking inside the former courtyard residence of Minister Chen’s grandfather at 1 Jingyang Beilu (景阳北路1号).
