Liujing Devonian section is located in Liujing Town, Heng County, Nanning City, Guangxi Province, next to Nanliu expressway. It is 50 kilometers away from the center of Nanning. It is a provincial geological site protection area, and also a natural scenic spot integrating science popularization, archaeology and sightseeing. It is a well-known Devonian standard section in China and also a world-famous Devonian standard section. The starting point of the profile starts from Xiayi mountain in the north of Liujing Town, passes through the railway station in the south, and then turns to Guguan village and Nazu village in the southeast, with a total length of about 3.5 km. There are two types of stratigraphic standard sections: deep water Devonian section and shallow water Devonian section. Liujing section has two sedimentary types of marine Devonian, which is the bridge of stratigraphic correlation between deep water Devonian and shallow water Devonian. It plays an important role in scientific research, teaching and international academic exchanges. In recent years, because of its rich content, clear geological characteristics, short section line and convenient transportation, it has become a place for students to practice and popularize Geoscience Knowledge. It is also an ideal place for the study of paleontology, stratigraphy, sedimentary facies and PALEOECOLOGY.

The standard section of Liujing Devonian system was formed during Devonian period (350-400 million years ago) of the earth's development history. Marine sediments rose to land through diagenesis and later crustal movement. All kinds of fossils we can see now are all kinds of organisms living in the ocean at that time. In the history of the development of the earth, there are very few chances for all kinds of organisms to be preserved as fossils. For example, Liujing Devonian standard section has many kinds of fossils, which are well developed, well exposed, and clear layers. Therefore, Liujing Devonian standard section is famous all over the world. The total exposed length of the basin surface is 4.6 km. The strata are divided into Lianhuashan formation, nagaoling formation, Yujiang formation, unnamed formation, Najiao formation, Mintang formation, Gubi formation, Rongxian formation and each group has its own characteristics. It is an ideal base for studying geology, sedimentology and popular science education.

Nanning is a subtropical monsoon region with abundant sunshine, abundant rainfall and mild climate. The average annual temperature is about 21.7 ℃, the coldest January in winter is 12.8 ℃, and the hottest July and August in summer is 28.2 ℃. The superior climate conditions make it evergreen and blooming all the year round, so Nanning is suitable for tourism all the year round. Therefore, the so-called "grass does not wither in winter, flowers do not bloom in spring" is not an exaggeration. It should be noted that Nanning is hot and humid in summer, especially in July and August, with an average maximum temperature of 30-38 ℃ and heavy rainfall. At this time, when you visit Nanning, you must prepare sunglasses, sun visors and corresponding rain gear. This section of traffic information Hengxian has a superior geographical location, and the waterway and land routes are relatively developed. It can be organized and arranged by the County Tourism Bureau, or arranged by oneself to take the buses of Hengxian passenger station of Nanning bus terminal, or connected with various private taxi cars and minibuses, which is very convenient. Nanning municipal government has increased investment in tourism in recent years. Businesses from all over the country have built many hotels and hostels near the nature reserve. The price is 30-80 yuan. There are seven hours of hot water supply every day, bath facilities, color TV, and 80 yuan rooms are air-conditioned. The environment is comfortable, clean and sanitary

Devonian strata are distributed all over the world, and the total amount of Devonian sediments is larger than that of other Paleozoic strata. Sedimentary strata are generally divided into old red sandstone facies, Rhine facies and Hercynian facies, which represent continental environment, nearshore and offshore marine environment respectively. Different basins have different sedimentary models. The lithofacies represented by the German Belgian basin are mainly nearshore and foreshore clastic facies in the early Devonian, shelf clastic facies, platform carbonate facies, basin argillaceous facies and underwater uplift carbonate facies in the middle and late Devonian. South China is similar to Western Europe, the difference is that in the middle and late Devonian, the platform was widely distributed with planktonic siliceous argillaceous and carbonate deposits, forming a paleogeographic pattern of platform basin crisscross. In the east of North America, on the contrary, the distribution of carbonate rocks in the early and Middle Devonian was shallow water, while in the late Devonian it was all deep water black shale and delta caskir facies. The Junggar Hinggan fold belt and Australia New Zealand geosyncline are dominated by island arc pyroclastic deposits. The special types of Devonian rocks include: ① old red sandstone distributed along the old red ancient land; ② reef limestone developed in Canada, Urals, Belgium and South China; ③ black shale widely distributed in North American platform; ④ manganese bearing siliceous rock in South China and graptolite shale in Early Devonian. Mango has oval fruit, light yellow skin and orange yellow flesh. The life span of the tree can reach three or four hundred years. Nanning is rich in mangoes. The mango produced here has tender endoplasm, sweet taste, thin skin and juicy. It is a high-grade tribute fruit. This section of Hengxian fish raw food, Liujing is a small town of Hengxian, where you can eat authentic Hengxian fish raw. Hengxian fish raw with color, shape and taste, exquisite knife skill, complete ingredients, choose raw River fresh (mainly grass carp in Dajiang River), also use river mud carp skin and viscera, cut into "Trojan horse rack" with bone, very crisp and sweet! First on the ingredients: fried peanuts, fried Guoba, fried taro silk.
