Dear Jack, 
I'm glad that your family like Chinese cuisine. 
Chinese cuisine is one of the most popular diets, but it can be high in oil and salt. What's more, main dish portions are often quite large, so you'd better order fewer dishes when you have dinner with your family in Chinese canteens. Then divide the dishes and eat up!
Choose dishes with lots of vegetables. You should try to avoid the dishes which have high calories, such as lamb kebabs and red braised pork belly. Ask the chef to use less oil, cut down on salt and cut out MSG.
Have a good appetite.
Yours,
Li Hua 

Dear friends, 
As we all know, we are what we eat. Therefore, it's very important for us to form healthy eating habits. However, bad eating habits are still very common among us students. Some don't have breakfast. Some prefer snacks. Some are particular about food and some eat or drink too much.  
To keep fit, we should have various healthy diets, which generally include proper amounts of fish, meat, vegetables, fruit as well as staple food. Besides, we'd better take meals at a regular time and eat a proper amount of food each time.
In my opinion, we should try to develop healthy eating habits. Only in this way can we have enough energy to study better.
That's all. Thank you!
