Dear Li Ming,
This Sunday we’ll go to the nursing home and did some voluntary labor. You were out, while I dropped in on you. However, I had to leave a message to you. According to the monitor said, we’ll meet at the gate of our school at 9:30 tomorrow morning and start out together with bike. So you should take their bike and don’t forget to take some washing powder, barber tools and weeding tool. We will help with washing clothes, cutting their hair and get rid of some weed in the garden. Lastly, you should remember to take some food for the lunch because we’ll stay here and chat with them at noon. If you come back, please phone me at once.
