### 3/5 — ‼️⚠️⚠️warning

*2024-06-30*

Developers can use ChatGPT to translate the English content of the app into Chinese. For example, they can inform ChatGPT that the context of the translation task is computer network technology. Based on the Chinese translation, they can develop an app update that supports Chinese in future versions.
