前端时间国外旅游，连不上国内的域名，导致没法记录。
建议可以在本地撰写，有网络时再上传。

Title: It is recommended to add offline writing mode

During the front-end time, I was traveling abroad and could not connect to the domestic domain name, resulting in the inability to record.
Suggestions can be written locally and uploaded when there is an Internet connection.
