The Shandong Peninsular constitutes the eastern part of Shandong, a province in the lower reaches of the Yellow River and a cradle of the Dawenkou and Longshan cultures about 4,000 years ago. During the Western Zhou (c. 1066-771 BC) Dynasty and the spring and autumn (770-476 BC) and Warring States (475-221 BC) periods, most part of Shandong became part of the states of Qo and Lu, which bequeathed a rich legacy on the land. Shandong abounds in tourist resources. Mount Taishan has made the UNESCO List of world cultural and natural heritage sites. Qingdao, Yanai, Weihai and Penglai are famed seaside tourist resorts. Shandong was also the homeland of Confucius and Mencius, two celebrated thinker of ancient China.
