+# 213_19 Fix broken and outdated links in development guides
+
+## 2025/02/27 Fix links in all platform development guides
+
+### What
+Fixed broken and outdated links across all six development guide files:
+- `Develop_on_Linux.md`
+- `Develop_on_Linux_ZH.md`
+- `Develop_on_macOS.md`
+- `Develop_on_macOS_ZH.md`
+- `Develop_on_Windows.md`
+- `Develop_on_Windows_ZH.md`
+
+### Why
+1. The English development guides for Linux and macOS incorrectly linked the testing section to the Chinese document `Test_ZH.md` instead of `Test_EN.md`.
+2. All six development guides linked the formatting guide to an external Gitee URL (`https://gitee.com/XmacsLabs/mogan/blob/main/devel/Format_ZH.md`), which is outdated since the project has migrated to GitHub under MoganLab. These should use local relative paths instead.
+3. The Windows development guides used a Gitee clone URL (`git@gitee.com:XmacsLabs/mogan.git`) instead of the current GitHub URL.
+4. The English Windows guide contained a Chinese word "验证" that should be "Verify".
+
+### How
+- Changed `Test_ZH.md` → `Test_EN.md` in English guides
+- Changed external Gitee formatting links → local relative paths (`Format_EN.md` for English, `Format_ZH.md` for Chinese)
+- Changed Gitee clone URL → `https://github.com/MoganLab/mogan.git` in Windows guides
+- Changed "验证" → "Verify" in the English Windows guide
