Why choose me
Own website
The projects uploaded on the website are all collected and developed by the bloggers themselves, and the quality can be guaranteed. It is suitable for students who know a little bit about program development!
My own small program (Xiao Cai coding)
In order to make it easier for students to use it, I developed a small program version called Xiaocai coding. Students can quickly search and locate the program they want through the mini program
