The smog was very serious in Zhengzhou the day before yesterday, so I stay at home all day. Today the sky is clear and the air is fresh , I can wander in the garden outdoor . How rarely the weather is! I hope that the smog should be less in the future.

1. That visible glory comes from invisible hard work.

2. A fast-moving yet comfortable-riding bullet train is powered by a hidden engine with ultra performance.
