From the legendary Yellow Emperor Yao Shun to the Xia Dynasty (about 2 1 century-BC16th century), painted pottery marked its development. Among them, there are typical Yangshao culture, Majiayao culture and Qijia culture later discovered in Gansu. After liberation, a large number of beautifully made painted pottery were unearthed from the prehistoric site in Anbanpo, Xi 'an, which was amazing. According to legend, Yao spread the world to Shun, Shun spread the world to Yu spread the world to his son and started the so-called "home world". Xia Chuanzhi was ruthless and tyrannical. Shang Tang released him and became emperor on his own, so he began to conquer the Tang Dynasty. Shang ruled the world for more than 600 years (about16th century BC-about1/century BC) until. After being conquered, he committed suicide and the world returned to Zhou. The ruling period of the Zhou Dynasty was roughly from1/century BC to 22 1 year BC, and the effective rule actually ended in 77 1 year BC. The period from 475 BC to 22 BC1year is called the Warring States Period. By 22 1 year BC, the Qin Dynasty had risen and unified China, but it lasted only 206 BC and was replaced by the Han Dynasty. During these thousands and hundreds of years, in addition to daily dining utensils, things used for sacrificial ceremonies have also developed greatly.
