At first, I thought about dividing a bit more, but the result was 60G, which is not enough now. I had to think about how to expand. There may be a way to expand the capacity in /home, but it will save trouble, just mount a folder directly!
Most of the content is based on the content in this blog, thanks to the wonderful sharing of the blogger, the actual measurement is effective. The blog is as follows: https://www.pianshen.com/article/59961583036/ link
One point in particular, when splitting under windows. Just select the disk to be partitioned first, and click "Compress Volume".
Enter after "Enter the amount of compressed space", the amount of space you want to allocate, if it is G, multiply by 1024. The estimated size before compression below may be larger than the one above, but this is normal (I don't know why, I don't dare to point it~).
After compression, a gray area will be generated. Right-click the area and click "New Simple Volume". All configurations are ok by default, and NTFS format will be generated by default, but there are ways to modify it in the blog above. Just refer!
Oh, awesome, it will be used for a while!
