Qiancheng is located in the mountainous area around the basin of the Sichuan Basin, with complex geological structure, belonging to the New China tectonic system, and obvious fold faults in the north-east direction. The main structures include Yangdong anticline, Maoheba anticline, Shaukitan anticline, Bamian Mountain anticline and Yushan anticline, the outcropping rock layer is based on the Sinian metamorphic rock system, until the Cretaceous, it has accepted the sedimentation of huge thick sedimentary rocks up to several thousand meters thick, and the outcropping strata and lithology are from old to new: the Lower Paleozoic is completely developed, the Cambrian and Ordovician are dominated by carbonate sedimentation, the Lower Middle and Old Remains are dominated by sand shale, with a thickness of 500 meters, and the Upper Devonian is marked by quartz sandstone and lacks Carboniferous; The Permian is undulating above the Middle and Laotian Lieu or Upper Devonian, dominated by limestone, and the bottom of the Upper and Lower Permian is sandwiched with shale, with a total thickness of about 1000 meters. The Triassic is continuously deposited in the upper Permian, the lower is limestone and dolomite, and the middle is purple sand shale, limestone and marl, with a total thickness of 1300 meters. The Jurassic is pseudo-integrated on the Triassic and is dominated by sand shale with a little bioclastic limestone. The Upper Cretaceous is sporadically distributed in the Zhengyang intermountain basin and is purple-red conglomerate. Quaternary strata are distributed near the modern riverbed, constituting the first and second terraces of the river, except for the river alluvium, generally only the moraine is controlled by the topography of the Qianjiang River area, and the trend of the mountain range is mostly consistent with the direction of the tectonic line, which is a north-east-southwest trend. From east to west, the mountains of Gray Qianliangzi, Wufuling, Qilingai, Bamian Mountain, Shantanggai and Jiajiao Mountain are nearly parallel, forming a landform of interspersed mountains and valleys. Most of the territory is dominated by low and middle mountains, with mountains accounting for about 85% of the total land area and hills accounting for about 10%, of which 5% of the area is river valley flat dams and intermountain basins. The mountains in the territory are undulating, the streams and rivers are vertical and horizontal, the mountains and valleys are intertwined, the terrain is high in the northeast, the southwest is low, the highest peak is 1938.5 meters above sea level, the lowest point is the Masikou of the Heixi River Valley, the altitude is 320 meters, the relative height difference is 1618.5 meters, generally 500-1000 meters, the layer is shallow - in the middle of the cutting of the middle and low mountain terrain. The main rivers are developed along the north-east-south-west valley, and their tributaries are distributed along the northwest-south-east valley. The main tributaries are distributed in a lattice pattern on the plane. The area above 1400 meters above sea level accounted for 4.04% of the area, 17.18% in the area of 1000-1400 m, 59.29% in the area of 500-1000 m, 14.45% in the area of 500-700 m, and 5.04% in the area below 500 meters.

This is Qiancheng, where Yang Chen grew up, and it is also the place he misses the most, Jinghua can't compare.
