1. The easiest way is to download version history version 3.0 on the microdisk (version 2.4.5 is not available, and other versions are not tested). As long as some services in Weibo are not disabled, you can authorize login normally without losing your password.

2. Sina microdisk has become a masterpiece, and there has been no book fragrance since then. I understand Sina's business strategy and can't say too much. The current copyright system seriously affects fairness.

3. Excellent information resources are monopolized by big cities and institutions, especially in China. It used to be books and periodicals, but now it is replaced by databases.

4. Because microdisk provides an equal, public and resource-rich information platform with tens of millions of academic books, papers and industry reports, it can be called the largest free public library in China.

Sina's announcement of closing microdisk doesn't mean that paying users can still search, but that paying users just don't delete their own data. Sina microdisk has completely become a backup network disk that cannot be shared, or a charging network disk with small capacity. There are only some materials such as postgraduate entrance examination and national examination.
