Mengda and Nan weren't worried about Zi Beiying and they trusted Xu Jinchen. They knew that Xu Jinchen wouldn't do anything inappropriate to Zi Beiying.
Even though they knew that, they actually hoped that Xu Jinchen would do something otherwise it might take forever for him and Zi Beiying to get together. There was chemistry between them after all, but neither of them took a step forward. Therefore, if they wanted to be together, one of them had to be more active and take the step ahead.
When they arrived at the entrance of the Great Wall, they had some food before going inside.
As long as it was a good day, there would be many visitors climbing up the Great Wall. Luckily, it wasn't a holiday, so there weren't a lot of people.
It was a good thing, because it would be impossible for them to appreciate the view if it was too crowded. Therefore, the amount of visitors was acceptable today. The Great Wall wasn't too quiet or noisy.
