Dear Lucy,
I am very excited to learn that you’re coming to Xi’an for travel. Both my parent miss you a lot. So is our friend, Ruby. April is best time of the year to visit Xi’an. There is only a few rain and the weather is neither too hot or too cold. There are so many places I wanted to take you to after I finish my work like a volunteer in the local charity. When you come, you can stay with ourselves. My house is about three kilometers far away from Xi’an Moslem Street where is full of local foods.
Best regards,
Janet
