Weihai, formerly Weihaiwei, is a prefecture-level city and major seaport city in easternmost Shandong province of China. It borders Yantai to the west and the Yellow Sea to the east, and is the closest Chinese city to South Korea.

Shandong is a coastal province in East China. Shandong has played a major role in Chinese history since the beginning of Chinese civilization along the lower reaches of the Yellow River. It has served as a pivotal cultural and religious center for Taoism, Chinese Buddhism and Confucianism. Shandong's Mount Tai is the most revered mountain of Taoism and a site with one of the longest histories of continuous religious worship in the world. The Buddhist temples in the mountains south of the provincial capital of Jinan were once among the foremost Buddhist sites in China. The city of Qufu was the birthplace of Confucius, and later became the center of Confucianism.
