China Standard Time
The time in China follows a single standard time offset of UTC+08:00 (eight hours ahead of Coordinated Universal Time), even though the country spans almost five geographical time zones. The official national standard time is called ''Beijing Time'' (BJT, ) domestically and ''China Standard Time'' (CST) internationally. Daylight saving time has not been observed since 1991. China Standard Time (UTC+8) is consistent across Mainland China, Hong Kong, Macau, Taiwan, Philippines, Singapore, Brunei, Mongolia, etc. History In the 1870s, the Shanghai Xujiahui Observatory was constructed by a French Catholic missionary. In 1880s officials in Shanghai French Concession started to provide a time announcement service using the Shanghai Mean Solar Time provided by the aforementioned observatory for ships into and out of Shanghai. By the end of 19th century, the time standard provided by the observatory had been switched to GMT+08:00. The practice has spread to other coastal ports, a ...

Chengdu
Chengdu (, ; simplified Chinese: 成都; pinyin: ''Chéngdū''; Sichuanese pronunciation: , Standard Chinese pronunciation: ), alternatively romanized as Chengtu, is a sub-provincial city which serves as the capital of the Chinese province of Sichuan. With a population of 20,937,757 inhabitants during the 2020 Chinese census, it is the fourth most populous city in China, and it is the only city apart from the four direct-administered municipalities with a population of over 20 million (the other three are Chongqing, Shanghai and Beijing).

1879 Gansu Earthquake
The 1879 Gansu earthquake occurred at about 04:00 local time on 1 July. It had an estimated magnitude of 8.0 on the scale and a maximum perceived intensity of XI (''Extreme'') on the Mercalli intensity scale. The epicenter was in Wudu District in southern Gansu, close to the border with Sichuan. It caused widespread damage and killed an estimated 22,000 people. Earthquake The earthquake was preceded by foreshocks in the few days before the mainshock. The meizoseismal area extends 70 km in a SSW-NNE direction and is 30 km across. The earthquake may have been caused by movement on the SSW-NNE trending Fanjiaba-Linjiang Fault. This fault correlates well with a 30 km long lineament seen on satellite images. The similarly oriented Hanan-Daoqizi-Maopola fault zone has also been proposed as a likely candidate. The earthquake triggered many landslides and caused the formation of several natural dams 40 to 120 m high. Damage In Wudu city there were a total of 9,881 ca ...

Orogeny
Orogeny is a mountain building process. An orogeny is an event that takes place at a convergent plate margin when plate motion compresses the margin. An '' orogenic belt'' or ''orogen'' develops as the compressed plate crumples and is uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called orogenesis. These include both structural deformation of existing continental crust and the creation of new continental crust through volcanism. Magma rising in the orogen carries less dense material upwards while leaving more dense material behind, resulting in compositional differentiation of Earth's lithosphere ( crust and uppermost mantle). A synorogenic process or event is one that occurs during an orogeny. The word "orogeny" () comes from Ancient Greek (, , + , , ). Although it was used before him, the term was employed by the American geologist G. K. Gilbert in 1890 to describe the process of mountain-building as distinguis ...

Min Mountains
Min Mountains or Minshan () are a mountain range in central China. It runs in the general north-south direction through northern Sichuan (the eastern part of the Ngawa Tibetan and Qiang Autonomous Prefecture and adjacent areas of Mianyang Prefecture-level city) and southernmost borderlands of Gansu. The highest elevation is Mount Xuebaoding ("Snow Treasure Peak"), 5588 m and the second highest is Mt Little Xuebaoding ("Little Snow Treasure Peak"), 5443m. Geography The Min mountain range is a southern prolongation of the Kunlun Mountains that separates the basins of two major rivers of Sichuan: the Min River (to the west) and the Jialing River (to the east). Both rivers flow in the general southern direction, and are tributaries of the Yangtze. The Min Mountains are part of a wider mountainous region: *Amne Machin: The range located to the far west, known to the ancient Chinese as Mount Jishi (積石山, 积石山, Jīshíshān), part of the Kunlun Mountains. * Xiqing Mo ...

Yangtze Plate
The Yangtze Plate, also called the South China Block or the South China Subplate, comprises the bulk of southern China. It is separated on the east from the Okinawa Plate by a rift that forms the Okinawa Trough which is a back-arc basin, on the south by the Sunda Plate and the Philippine Sea Plate, and on the north and west by the Eurasian Plate. The Longmenshan Fault on the latter border was the site of the 2008 Wenchuan earthquake. The Yangtze Plate was formed by the disaggregation of the Rodinia Supercontinent 750 million years ago, in the Neoproterozoic era. South China rifted away from the Gondwana supercontinent in the Silurian. During the formation of the great supercontinent Pangaea, South China was a smaller, separate continent located off the east coast of the supercontinent and drifting northward. In the Triassic the Yangtze Plate collided with the North China Plate, thereby connecting with Pangaea, and formed the Sichuan basin. In the Cenozoic the Yangtze Plat ...
