First, these treasures come from Chang 'an. Liu He was the emperor for 27 days before he got seasick, so some experts and scholars think that these treasures of Liu He were probably brought from Chang 'an. However, it was suggested that when Liu He was driven out of Chang 'an, there were basically no cronies around him. He can't bring so much treasure out by himself.
Second, these treasures come from the old country of Changyi. Liu He was a vassal state of Changyi before he proclaimed himself emperor, and many historians agree that the treasure came from here. Liu He's treasure was probably sent to Changyi for retrieval after he was banished to the sea.
No matter which of these two views can be established, it is certain that the source of these treasures is definitely inappropriate. These treasures were obtained by plundering the wealth and essence of the people at that time. Do you think that as a vassal of the Han Dynasty, how can you have so much time and energy to earn these treasures? It was probably obtained by taxing farmers and plundering some rich people at that time. However, these treasures can still provide some reference for future generations to study the economic level at that time!
