Dear Mr. President,I'm very lucky to be studying in this world-famous university, but I'm afraid I'm not content with the canteen service on campus.Firstly, there is little variety in the food served.Undoubtedly, there are a lot of delicious dishes, but they remain the same all the year round.More and more students are complaining about eating the same food every day.So I think the most urgent problem to be solved is variety.Secondly, the price is a bit too high.Many of us hope that the canteen can provide us with not only delicious but also less expensive food.The above suggestions are not just of my own, but also of many other students.We hope our respected president will give our suggestions consideration.Yours faithfullyLi Ming
