求翻譯：Some people think it is safe by saving money in the bank. And some people think it is better to use the money to invest. I think if I have a lot of money, I will save half in the bank and then use another half to invest. Why? All us know invest is with risk. We can earn more money and we can lose money as well. We have to have enough money to keep our life first then to invest. Even if we lose money, we still have money to live in. This is my opinion. That's all.
