According to a survey conducted by China Youth Daily, 88.9% people are willing to exchange skills, and 5 1.2% of them choose "financial knowledge". 50.9% people want to learn "computer skills such as computer maintenance and software"; 40.6% people want to exchange "foreign language skills such as English and Japanese". According to some "skills exchange" websites in the island city, most citizens who participate in "skills exchange" want to exchange and learn foreign languages, among which English, Japanese, Korean and other languages are the most popular. Browsing the island city exchange website, I learned that most of the participants in the "skills exchange" are post-80s and post-90s, mainly college students, white-collar workers in the workplace, and some junior high school students. Netizens who participate in "skill exchange" are usually called "technical customers".
