1、首先要明确一点，qq空间并没有提供一次性删除所有说说的功能，但提供了封存动态的功能，封存以后的说说数据还是存在的，也就可以恢复的，但是其他用户无法访问，间接的等于删除了说说。操作方法是首先需要登录qq空间，点击导航栏中的说说选项：
/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a1339bea074f903918fa1ecc0fa"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a1339bea074f903918fa1ecc0fa?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/562c11dfa9ec8a1339bea074f903918fa1ecc0fa"/>
2、进入说说以后直接点击点击右上角的设置按钮，进入说说的设置选项：
/iknow-pic.cdn.bcebos.com/38dbb6fd5266d01605af68bc992bd40734fa35eb"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/38dbb6fd5266d01605af68bc992bd40734fa35eb?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/38dbb6fd5266d01605af68bc992bd40734fa35eb"/>
3、最后在说说的设置里找到并点击封存我的动态选项，并点击开启选项：
/iknow-pic.cdn.bcebos.com/00e93901213fb80ed092914338d12f2eb83894e7"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/00e93901213fb80ed092914338d12f2eb83894e7?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/00e93901213fb80ed092914338d12f2eb83894e7"/>
4、接着设置封存的时间，选择自己想要封存的时间段，点击说说的选项，将前面的对勾打上以后，屏幕出现设置成功即可全部删除说说了：
