Collecting stamps is educational!
Yesterday was Show and Tell Day at Daniel's school.
Daniel was the first student to speak. He showed his classmates an old stamp.
"My father gave me this first stamp," said Daniel. "It has a picture of an old Chinese stone bridge on it. This made me more interested in Chinese culture. Soon I started to look for more stamps with interesting pictures."
"Now I have over 100 stamps," said Daniel. "I learnt a lot about our country and its great culture from the stamps! Collecting stamps is really educational."
"That was a great talk. Thank you, Daniel," said the teacher.
