Zhoushan in the context of "Ningbo"

"Mainland China" is a geopolitical term defined as the territory under direct administration of the People's Republic of China (PRC) in the aftermath of the Chinese Civil War. In addition to the geographical mainland, the geopolitical sense of the term includes islands such as Hainan, Chongming, and Zhoushan. It is also important to note that the terms "the Chinese mainland" or "the mainland of China" are preferred by explicitly pro-Beijing bodies, while the more common term in the English-speaking world and in Taiwan, Hong Kong, and Macau is "mainland China".

By convention, territories covered by the term exclude:

The Port of Ningbo-Zhoushan is the busiest port in the world in terms of cargo tonnage. It handled 888.96 million tons of cargo in 2015. The port is located in Ningbo and Zhoushan, on the coast of the East China Sea, in Zhejiang province on the southeast end of Hangzhou Bay, across which it faces the municipality of Shanghai.

The port is at the crossroads of the north–south inland and coastal shipping route, including canals to the important inland waterway to interior China, the Yangtze River, to the north. The port consists of several ports which are Beilun (seaport), Zhenhai (estuary port), and old Ningbo harbor (inland river port).

Religion in China is diverse and most Chinese people are either non-religious or practice a combination of Buddhism and Taoism with a Confucian worldview, which is collectively termed as Chinese folk religion.

The People's Republic of China is officially an atheist state, but the Chinese government formally recognizes five religions: Buddhism, Taoism, Christianity (Catholicism and Protestantism are recognized separately), and Islam. All religious institutions in the country are required to uphold the leadership of the Chinese Communist Party (CCP), implement Xi Jinping Thought, and promote the Religious Sinicization under the general secretaryship of Xi Jinping. According to 2021 estimates from the CIA World Factbook, 52.1% of the population is unaffiliated, 21.9% follows Chinese Folk Religion, 18.2% follows Buddhism, 5.1% follow Christianity, 1.8% follow Islam, and 0.7% follow other religions including Taoism.

Hangzhou Bay is a funnel-shaped inlet of the East China Sea on the middle eastern coast of Mainland China, bordered by the province of Zhejiang to the west and south, and the municipality of Shanghai to north. The bay extends westwards to its head at the city of Hangzhou, the provincial capital of Zhejiang, from which its name is derived. The east and southeast margin of Hangzhou Bay are marked by numerous islands off the shores of Ningbo, collectively called the Zhoushan Islands, which are an urbanized archipelago that forms the prefecture-level city of Zhoushan.

At Hangzhou, the Qiantang River flows into the bay, providing fresh water from the west, while seawater comes in from the east. Thus, Hangzhou Bay, especially its western end, is sometimes called the Qiantang River Estuary in the scientific literature.

Mount Putuo (Chinese: 普陀山; pinyin: Pǔtuó Shān, from Sanskrit: "Mount Potalaka") is an island in Putuo District, Zhoushan, Zhejiang, China. It is a renowned site in Chinese Buddhism and is the bodhimaṇḍa of the bodhisattva Guanyin.

Mount Putuo is one of the four sacred mountains in Chinese Buddhism, the others being Mount Wutai, Mount Jiuhua, and Mount Emei (bodhimaṇḍas for Manjushri, Kṣitigarbha, and Samantabhadra, respectively).

Yangshan Port (Chinese: 洋山港, p Yángshān Gǎng, Wu Yan-se Kaon), formally the Yangshan Deep-Water Port (洋山深水港, p Yángshān Shēnshuǐ Gǎng, Wu Yan-se Sen-sy Kaon), is an offshore deep-water port for containerization in Hangzhou Bay south of Shanghai, China, built on land reclamation joining the Lesser Yangshan Island with numerous other nearby islands of the northwestern Zhoushan archipelago. It is connected to Shanghai's Pudong New Area on the mainland by the 32.5 km-long (20.2 mi) Donghai Bridge, forming part of the Port of Shanghai, while the other islands of Yangshan archipelago (including the Greater Yangshan Island, where the civilian population of the archipelago live) are administered separately as part of Zhejiang's Shengsi County.

Yangshan Port is part of China's Maritime Silk Road, built to allow the Port of Shanghai to grow despite shallow waters near the shore. Prior to its construction, the Port of Shanghai was predominantly based around the mouth of the Huangpu River, which is too shallow to handle large container ships, forcing the port to often perform mid-stream operations within the Yangtze estuary, which often had to wait for the high tide hours, severely restricting the port's capacity. The construction of Yangshan Port allows berths with depths of up to 15 m (49 ft) to be built, and can handle today's largest container ships. In mid-2011, port officials said the port was on track to move 12.3 million twenty-foot equivalent units (TEUs) during the year, up from 10.1 million TEUs in 2010, overtaking Port of Singapore to become the world's busiest container port. In 2015, the port handled 36.54 million TEUs, and by 2019, its throughput had increased to 43.35 million TEU.
