Stayed in Lanzhou for a month, went to the Gansu Provincial Museum three times, still feel that the meaning is still not enough. Be sure to listen to the explanation, I listened to it twice. The most famous is the horse stepping on the swallow. With a whole set of copper cars and horses, it was unearthed in Wuwei's Leitai Han Tomb. For this reason, I went to Wuwei. The left side of the highway is the rolling Qilian Mountains. You can also see the magnificent Maya Snow Mountain, passing through the layers of Wushu Mountain. What appeared in front of you was a large plain, which was the ancient Liangzhou, "the Yellow River far above the white clouds, a lonely city Wanli Mountain"; "Grape wine night light cup, general wants to drink immediately", in this land, young general Huo went to the disease several wars to defeat the Hunnu, seal the wolf to live, ensure the border peace, so that the Silk Road can flourish. The vast and desolate land, the history of singing and crying, is extremely fascinating.
