每一個人的權利義務是各自負擔，如果成年子女已滿18 歲而有完整行為能力時，所有的行為都應由自己負責，所以父母是沒有幫成年子女清償債務的義務
喔！
Everyone is responsible for their own rights and obligations. If a child is already 18 years old and has full legal capacity, then they must take responsibility for their own actions and debts. Therefore, under the law, parents are not obligated to pay off their adult child's debts.
