+1. Why is the content empty after deployment?
+   - Check if the channel is public, it must be public
+   - The channel username is a string, not a number
+   - Turn off the "Restricting Saving Content" setting in the channel
+   - Redeploy after modifying environment variables
+   - Telegram blocks public display of some sensitive channels, you can verify by visiting `https://t.me/s/channelusername`.

+
+1. 为什么部署后内容为空？
+   - 检查频道是否是公开的，必须是公开的
+   - 频道用户名是字符串，不是数字
+   - 关闭频道 Restricting Saving Content 设置项
+   - 修改完环境变量后需要重新部署
+   - Telegram 会屏蔽一些敏感频道的公开展示， 可以通过访问 `https://t.me/s/频道用户名` 确认
