Possible Version 1:

Dear Chris,

I’m more than happy that you’re coming to China for your further study! You will surely learn a lot about China and its culture in the following few years.

Both Beijing and Guangzhou are good places to study in, but I strongly recommend that you come to Guangzhou. This city has dozens of famous universities for you to apply to, and you can learn not only Mandarin but also the local dialect Cantonese, which will add to the pleasure of your studying.  

Since I’ve decided to study in Guangzhou, we can meet frequently if you study there, too. Wouldn’t that be amazing!

Hopefully these can help you make your final decision. Looking forward to meeting you here in China.

Both Beijing and Guangzhou are good places to study in, but I strongly recommend that you come to Beijing, which has so many famous universities for you to apply to. Besides, it offers a better environment for Chinese learning since most people here speak standard Mandarin. I’m also planning to study in Beijing so I believe we can meet from time to time if you decide to study there. Wouldn’t that be amazing!

Hopefully these can help you make your final decision. Looking forward to meeting you here in China.
