可以一直保存。微信的图片、文字、语音等，一般情况下是可以一直保存的，如果你将聊天记录删除的话，则没办法查看了。
查看微信聊天记录的方法：
1、打开微信点击“通讯录”。找到你要查询的好友，点进去。

2、在与好友的聊天页，点击右上方的图示。

3、找到“查找聊天记录”，然后点击加入。

https://iknow-pic.cdn.bcebos.com/6d81800a19d8bc3ea6fab9818e8ba61ea9d3458e"/>
4、此时已可以查找聊天记录。有两种方式查询，一是搜索关键字，二是按日期查询。

https://iknow-pic.cdn.bcebos.com/0df3d7ca7bcb0a465fb934726763f6246a60afe6"/>
5、以日期查询为例。点击日期，进入日期界面，选择你要查的那天就会出现聊天记录（注意：浅灰色日期没有聊天记录）。
