How do you understand that traveling means spending money to buy hard work?

It depends on your mentality. Traveling is for experience. Spending money to travel is like paying tuition. What you learn is of course your own. Also, if you are traveling alone, it can help you understand the scenic spots and historic sites while also understanding yourself and experiencing life. Many of the famous poems and classics in ancient times were written by the authors after traveling. If it's a few friends or a family, it can give everyone the opportunity to get to know each other more deeply. Promote friendship.
