I think if you know more about history, it's worth visiting. History flavor is very strong. The underground palace of Qingdong Mausoleum is amazing! His exquisitely constructed fresco carvings have been designed in style. It's a miracle of the world. No one has come before or after. It's too big for a tourist car to sit in, or you're tired! They also caught up with the sacrificial performance. It's good.
