delicacies吧

你的字好整齐，羡慕

生僻与否是相对 学生年级的。
我个人感觉，数处写得很绕不简洁(凑字数的感觉)

楼主在说反话，其实是希望我们给他点赞，他那点小心思瞒得了别人，瞒不了我。
不过确实有很多怪异之处，my local cuisin是一个，have fun with the present， your satisfactory feedback也是，请作文的笔者解释一下是什么意思吧。

用简单常用的词表达出丰富的内容才是高手。而且要记固定搭配，不能自已创造出一些可能连外国人都看不懂的短语。

楼主还是高中/初中生吧？写成这样非常了不起了。各种语法结构用的666。我没觉得用复杂了
有些word choice有点问题，但总体厉害了

我给你大概改下。Knowing that you're interested in the food of my hometown, I bought you a recipe book of it.
The book is in English, and it contains a variety of receipes across the country. You'll have a taste of many speical dishes in different regions. If you turn to Page 43, you will find a receipe of the food in my hometown.

I sent the book to you by EMS the day before yesterday, and it should arrive at your place on Money.
Have fun reading the book! I can't wait to hear your opinion of it.
Best Regards
Lihua

satisfactory有勉强可以的意思，在这里不合适

before 换成in front of

求衡水体如何练的字写着写着就飘了

主要问题不在这，就是感觉有点啰嗦，可以删减一些句子，词不够的话适量扩充内容

语句可以精简些，和我以前写作文一个样 ，想着要短短长搭配，结果长不了强行长
