This Yuan Dynasty temple dedicated to immortal Lü Dongbin features grey-brick architecture blending northern folk style with Taoist aesthetics. The real treasure? You'll have Ming Dynasty frescoes all to yourself with barely any tourists. Chat with resident Taoist priests or rub the century-old scholar tree at the entrance - locals believe it brings luck. Perfect for an off-the-beaten-path spiritual experience!
