There are many ways. Generally, Baidu searches for PPT downloads, and then clicks in one by one. Some websites have free downloads for new registered members and can be used. There is also a network disk search (there is a special network disk search website, you can Baidu yourself). The third is that there are some PPt templates in Baidu library. Good luck.

Or what kind of ppt you need, you can also ask, maybe there is a suitable sharing.
