Few people play idle fish, but 99% of them have been used in Taobao, JD.COM. Both apps have their own currencies, such as JD.COM's Jingdou and Taobao's gold coins. Both are the same as small yellow croaker in salted fish. They buy things in their own applications as money. For example, I deducted about 100 yuan from Jingdou in JD.COM during the Double Eleven last year, while idle fish is a second-hand platform, so the deduction ratio is relatively small, and generally only five small yellow croaker can be used.
Therefore, 0.0 1 small yellow croaker is the value of 0.0 1 of salted fish coin, and shopping can be used as money.
