Eastern China in the context of Military logistics

The Pearl River Delta Metropolitan Region is the low-lying area surrounding the Pearl River estuary, where the Pearl River flows into the South China Sea. Referred to as the Guangdong–Hong Kong–Macao Greater Bay Area in official documents, the region is one of the most densely populated and urbanized regions in the world, and is considered a megacity by numerous scholars. It is currently the wealthiest region in Southern China and one of the wealthiest regions in China along with the Yangtze River Delta in Eastern China and Jingjinji in Northern China. Most of the region is part of the Pearl River Delta Economic Zone, which is a special economic zone of China.

The region is a megalopolis, and is at the southern end of a larger megalopolis running along the southern coast of China, which include metropolises such as Hong Kong, Shenzhen, Guangzhou, and Macao. The nine largest cities of the PRD had a combined population of 86 million in 2022; the PRD has become the largest urban area in the world in both size and population. The region's traditional language is Cantonese; in the late 20th century and the 21st century, due to the high inflow of migrant workers coming from other regions, Mandarin has gradually become a lingua franca.

Yonglongsha, sometimes translated as the Yonglong Shoal or Yonglong Sands, was a former island in the north channel of the Yangtze River to the north of Chongming in eastern China. It was also known as Yongfengsha and Hefengsha. Prior to its absorption by Chongming, it measured about 16 kilometers (9.9 mi) east to west but was very narrow, with an area of about 14 km (5.4 sq mi).

The Reorganized National Government of the Republic of China, commonly described as the Wang Jingwei regime, was a puppet state of the Empire of Japan in eastern China. It existed coterminous with the Nationalist government of the Republic of China under Chiang Kai-shek, which was fighting Japan alongside the other Allies of World War II. The country functioned as a dictatorship under Wang Jingwei, formerly a high-ranking official of the Kuomintang (KMT) party. The region it administered was initially seized by Japan during the late 1930s at the beginning of the Second Sino-Japanese War.

Wang, a rival of Chiang Kai-shek and member of the pro-peace faction of the KMT, defected to the Japanese side and formed a collaborationist government in occupied Nanjing in 1940, as well as a concurrent collaborationist Kuomintang that ruled the new government. The new state claimed the entirety of China (outside the Japanese puppet state of Manchukuo) during its existence, portraying itself as the legitimate inheritors of the Xinhai Revolution and Sun Yat-sen's legacy as opposed to Chiang's government in Chongqing, but effectively only Japanese-occupied territory was under its direct control. Its international recognition was limited to other members of the Anti-Comintern Pact, of which it was a signatory. The Reorganized National Government existed until the end of World War II and the surrender of Japan in August 1945, at which point the regime was dissolved and many of its leading members were executed for treason.

The Bohai Economic Rim (BER) or Bohai Bay Economic Rim (BBER) is the economic region surrounding Tianjin (Tientsin). It also includes areas in Hebei, Liaoning and Shandong surrounding the Bohai Sea. This region has undergone major economic and infrastructural changes and is an emerging economic powerhouse of North China, rivaling both the Pearl River Delta in southern China and the Yangtze River Delta in eastern China.

Qian, also variously spelt Ch'ien, Chien, Chin, Tsien, and (from its Wu pronunciation) Zee, is a common Chinese surname. It is particularly common in Eastern China, where members of the family ruled from Hangzhou as kings of Wuyue in the 10th-century interregnum between the Tang and Song dynasties. In 2008, Qian was the 96th most common surname in mainland China, shared by 2.2 million people, with the greatest concentration of Qians being in Jiangsu Province.
