The state organizes the excavation of ancient tombs, and all unearthed cultural relics belong to the state, and no individual may possess them. Unearthed cultural relics should be kept in museums established by the state and cannot be bought or sold as personal property. Unearthed cultural relics have two main functions. One is for scholars to study and provide physical evidence for historical research, which is very important for us to understand the history of national development. Now, we haven't found the historical sites of the Xia Dynasty. If we find the ancient tomb of Xia Dynasty, we can prove the existence of Xia Dynasty. However, it is estimated that the tombs of the Xia Dynasty were stolen by grave robbers, and the state could not confirm whether the Xia Dynasty really existed. If the country excavates ancient tombs in a planned way, it can restore the true history. The second is to let the people visit and let everyone know the glorious history of our nation. Personal robbery is not for research. Stolen tomb relics were sold by grave robbers for personal gain, and the country also lost the opportunity to study history through tomb relics. So the country must not allow individuals to dig ancient tombs! This is not a question of money, but whether we can find out the ancient history. Individuals dig ancient tombs, cultural relics belong to themselves, and reselling is theft, which means stealing national treasures.
