How to persuade parents to plan to travel abroad?

Let them know your ability to travel alone. In the past six months, I earned enough money for my next trip and took my mother to Japan. After coming back, my mother told my father that your daughter is very powerful and she can do it alone. So now I'm telling my parents that I'm going to travel abroad, and my mother will send me the materials I need directly, and I've prepared several more copies, saying that I won't ask us for a visa next time.
