Dear Grandpa,

    Thank you for the new jeans. They are cool! It's cool in Beijing. I can wear my jeans and T-shirt.  

I have a new jacket. My old jacket is too small. I want to buy a pair of sneakers. They are fifty yuan.

They are too expensive. What's the weather like at the farm? Is it warm?

                                                                                                                                             Love,

                                                                                                                                             John
