若要徹底清空微信資料來增加更多的記憶空間，單純的刪除聊天紀錄並不能達到目的。首先，進入微信主畫面的「設定」選項，接著進入「儲存空間」。然後，將快取、聊天紀錄以及與其他帳號的聊天紀錄進行清理。這樣，資料就能真正被刪除。當手機空間不足時，微信也會自動提示清除這三種暫存資料。

To thoroughly clear WeChat data to free up more memory space, simply deleting chat records won't achieve the desired result. First, go to the "Settings" option on the WeChat main screen, then navigate to "Storage Space". Next, proceed to clear the cache, chat records, and chat records with other accounts. This way, the data will be truly deleted. When the phone's storage space is insufficient, WeChat will also prompt to automatically clear these three types of temporary data.
