Shenzhen Sanshui Line is difficult to walk.

Sanshui Line is one of the longest crossing lines in Shenzhen in one day, extending along the ridge at the junction of Shenzhen and Huizhou. Passing through interesting place names, such as Sanpen, Huoshaotian, Earth Temple, Jingui Village and Shuizukeng, it covers the "five elements" of Jin Mu. Crossing is difficult, it takes about 8 hours to complete, and there is no water supply point on the way. But the beautiful scenery is one of the routes that many hikers must take, and it is also the goal that some hikers challenge.
