Last Sunday, we had a good weekend. My grandparents, my parents and I went to Beihu Park. 

It's very big and beautiful. We went there by bus. My grandma and my mum walked slowly in the park. My grandpa and my dad played chess under the tree. I met some friends. We flew kites together. It was sunny and we played very well!
