Tom wants to visit the Great Wall next year, but he doesn't know when to visit it. So he asks his Chinese friend about it by email. Some days later, he gets an email:
The best time in a day
Many people visit the Great Wall every day. The busy time of visiting the Great Wall is from 10:00 a. m. to 3:00 p. m. There are too many people there during (在……期间) that time. So you can go there early in the morning or late in the afternoon.
The best months in a year
Usually, the travel season (旅游季) is from May to October in Beijing. Of these months, May and October are the best months to visit the Great Wall. The weather is always sunny and warm in the two months.
