Teacher Liang was already waiting for us at the meeting point and thoughtfully provided detailed directions, making it easy for us to find the meeting point. During the tour of Baiyuan/Longmen Grottoes, through professional content, simple explanations, and the aid of pictures, she gave us a different understanding of Bai Juyi and Longmen Grottoes than what we had learned in books. She worked tirelessly for the entire four hours without a break (and even went overtime to explain things to us, tourists from other places, so that we could learn more). At the end, Teacher Liang specifically mentioned that the protection of cultural relics is closely related to the country's national strength. She said that every cave and every Buddha in Longmen Grottoes is telling us, the descendants, stories from thousands of years ago. My wife and I completely agreed. It was truly an honor to have such a good guide.
