亲爱的姥姥：
Dear grandma
您好！
Hello!
运动使人健康。这是您常说的可您却没有运动，只想去打麻将，这对您的伤害非常大，我十分担心您。
Exercise makes people healthy. This is what you often say, but you don't exercise and only want to play mahjong, which will cause great harm to you. I am very worried about you.
首先打麻将是十分害钱的，您获胜了，会觉得您下一把一定也能获胜，如果输了，会觉得下一把一定能获胜，就这样循环下去。一直到你没钱，没有钱了才会停下。而且打麻将也会伤害你的身体。能打麻将，一打就是一下午。久坐不动，可能会对您的腿造成伤害。老了以后可能会得关节炎，一走路就疼，这是十分难受的，这样我们就不能一起去做农活，一起去玩了。
First of all, playing mahjong is very harmful to money. If you win, you will feel that you will definitely win the next game. If you lose, you will feel that you will definitely win the next game, and this cycle continues. You won't stop until you run out of money. Moreover, playing mahjong can also harm your body. I can play mahjong for an entire afternoon. Sitting for too long may cause harm to your legs. As we get older, we may develop arthritis, which can cause pain every time we walk. This is very uncomfortable, so we can't go to do farm work or play together.
您可以让外公提醒您不要去打麻将，或是写张纸挂在床头纸上写，不能去打麻将，这几个大字每天早上起来就能提醒自己运动，也可以保持健康，您可以每天早上去跑步，晚上吃完饭也可以出去散步。
You can ask your grandfather to remind you not to play mahjong, or write a piece of paper hanging on the bedside paper to say that you cannot play mahjong. These words can remind you to exercise every morning and keep you healthy. You can go for a run every morning and take a walk after dinner at night.
以后在寒暑假的时候，我会和妈妈哥哥回老家帮助您，戒掉打麻将，让生活更加美满幸福，希望您快速能快速戒掉打麻将，这个坏习惯。也希望您身体健康。
Later, in winter and summer vacation, I will go back to my hometown with my mother and brother to help you, give up playing mahjong, and make your life more happy. I hope you can quickly give up playing mahjong, a bad habit. I also hope you are in good health.
祝

身体健康，万事如意！
Good health and all the best!
