Sign up on Trip.com, start from Xi'an with the group and enjoy VIP treatment very, very good. The road is safe and smooth, and the beautiful scenery on both sides of the road keeps passing by. The super shocking Yellow River Hukou, although I have done enough homework and have full mental preparation, I was still strongly shocked. It is really spectacular and handsome! [View] Very beautiful. [Fun] High. [Cost-effective] Absolutely high.
