Exchange based tourism has become popular. The May Day holiday that has just passed has left many people amazed by the skyrocketing hotel costs.

At the end of April, Ms. Li, who lives in Beijing, posted a short video on social media, Open solicitation of a "friend who can exchange for a trip", with only one additional condition for exchange: watering the flowers in the yard. After the video was released, it attracted the attention of many netizens, with thousands of related comments. Ms. Li's private message was also filled with eager netizens.

Before Ms. Zheng arrived, Ms. Li had originally provided her with some travel guides for Beijing attractions.
