Dear Lisa,

     I'm glad to have received your letter. Our holiday life has changed a lot. Learning and relaxing are still very important to us. Besides, we often help our parents do housework or farm work. Through that, we realise how hard our parents work every day. And we can make a habit of laboring at the same time. Also, we take an active part in social activities as volunteers. Sometimes, we go to the streets to collect rubbish or go to the hospital to cheer up the sick children. We try our best to help people in need and make our hometown more beautiful. We find great pleasure in all these activities.

     Best wishes!

Yours
Li Ming
