我操作過的保存方法：
第壹：打開微信聊天記錄，然後選自己想要的視頻。

第二：選住自己想要的視頻後，長按視頻點擊收藏，然後在收藏裏妳就可以看到了。 /iknow-pic.cdn.bcebos.com/48540923dd54564e39bc3ddfbfde9c82d0584f7f"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/48540923dd54564e39bc3ddfbfde9c82d0584f7f?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/48540923dd54564e39bc3ddfbfde9c82d0584f7f"/>
第三：點下方“我的”，看到這個頁面，點擊收藏進入。進入我的收藏之後，點擊妳剛才收藏的視頻，長按。
