Qinglang is a Chinese programming language aimed at teenagers, children and non-professionals.

The project completely realized the construction of code text to syntax tree from scratch. The language core refers to Lisp, and the syntax mainly refers to JavaScript. It is implemented in C# and runs on the .Net platform.

Qinglang is fully compatible with mainstream operating systems. In addition to interpreters, it also provides Qinglang editors and mobile apps. In addition, we also provide detailed documentation, including usage documentation and development documentation.
