The trip with guide Ian was fulfilling and fun. Since it was the Labor Day holiday, the bus was completely full, and there were many Korean groups. He explained in English and Chinese, so I concentrated as if taking a listening test and studied history. If you come to Beijing, you must take the Gubei Water Town tour. It's truly incredibly vast, unique, and every place is a photo opportunity. I was also surprised by how massive the Great Wall was when we went up by cable car. I was worried that I would only see the backs of people's heads due to the Labor Day holiday, but perhaps because it was raining and cold, there were actually very few people, which was even better. It's a place you can fully enjoy even without a Korean guide.
