Her parents were sad at that moment. People were happy at that time. My friends are impatient today. Mary was fat when she was five. Hai Zhang was short when he was young, but now he is quite tall. The town was clean 20 years ago, but it is now dirty and polluted. Mr. He was in his offic half an hour ago. Han Gang's father was very angry yesterday afternoon. Was your sister in Beijing at that time? No, she wasn't. They were not at school 25 minutes ago. Shanghai was clean and beautiful at that moment. The air of this city is dirty, so are the rivers and buildings. Now the streets are not orderliness, but crowded. We were not happy then, but we are now. That place was beautiful and peaceful 6 years ago.
