Though it's still about a month to go, it might be useful to practise this before the Valentine's day. If you want to go further from merely saying "I Love You", which we taught previously, you don't want to miss this post.
I am from China and currently doing my Ph.D. in US. Assisting my wife in teaching Chinese gives me a lot of fun and makes me love my home language and culture even more. Actually, mastering the daily use Chinese (Mandarin) is just easy, not like you are going for a Ph.D., right? :) It just requires some dedication to practice. Wish you all good luck!
You are more than welcome to point out my mistake in English, and I will be so happy to learn from you guys, too:)
