It is not known for certain if the Xia dynasty actually existed. Many people think that the Xia dynasty is only a legend. This is because there is no evidence that can prove that there was some dynasty before 1600 BC. There were found some archaeological excavations from 1500 BC which may come from the Xia dynasty. For example one of the excavations causes archaeologists to believe that the foundations of China were created during the Xia dynasty. Also there are findings of the oldest Chinese calendar called a lunar calendar. Xia dynasty was ended by a dynasty named Shang.
Shang dynasty.
The Shang dynasty lasted from 1600 BC until 1046 BC. It started when Tang took control from the last Xia emperor, Jie. The dynasty ended with the suicide of Di Xin.
The Shang dynasty was important for Chinese culture. The first Chinese character fonts were created at this time. They were mainly used by seers and shaman. People made their own ritual vessels, agricultural and craft tools and even weapons. Everything was made of cast bronze.
In agriculture, millets, wheats and rice were the main crops. Mulberries were also grown. They were used to feed mulberry silkworms.
Zhou dynasty.
The Zhou dynasty lasted from 1045 BC until 256 BC. The Shangs had became weak because they were always fighting with a neighboring tribes. This was good for the less advanced Zhou.
