I recommend Nannuo mount. We spent 2 days in this area, enjoyed the trail up hill through the tea tree plantation, saw the king tea tree aged 800 years and got a bit of the villages peaceful atmosphere. The Pu’er tea from Nannuo is quite famous in the region for its quality. So you need to give it a try! It is easy to access through DiDi. The directions to the trail that goes to the king tea tree are available in both Chinese and English.
