What is the best personal information management software? What personal information management software are there? What does personal information management mean?

I don't know much about it either, but I know that personal information management is financial management plus contact and schedule time management. I saw a lot of software called personal information management on Huajun Dortmund, and it is very common to download and use it. However, the newly updated software has a nice personal assistant called Jiameng 3. 1. Just try it. I think the last personal information management I used was this software. Huajun, Dortmund and Sina all have it. Find it yourself.
