Suggest adding a promotion system to Daokebaba

Daokebaba is a very good online sharing platform for electronic documents. Many of the latest documents can not be found in Baidu Library, but can be found in daokebaba, so I use daokebaba most to find documents. Today, I made a suggestion to daokebaba, suggesting him to increase the document promotion system, increase the exposure of platform documents and the number of sharing and downloading, which is very helpful to improve the overall income of daokebaba.
