My trip with guide Ian was fulfilling and enjoyable. Since it was Labor Day weekend, the bus was completely full, and there were many Korean groups. He explained in English and Chinese, so I focused on learning history as if I were taking a listening test. If you come to Beijing, you must take the Gubei Water Town tour. It's truly vast, unique, and every spot 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 I'd only see the backs of people's heads due to the Labor Day holiday, but it was actually great because there weren't many people, perhaps due to the rain and cold. It's a place you can thoroughly enjoy even without a Korean-speaking guide.
