The reason why there is no one in Changshu Street is the influence of weather and epidemic situation.

1, weather reason: If it is too hot or too cold, people don't want to stay outdoors for too long, so there will be relatively few people on the street.

2. Epidemic impact: If there is an epidemic in the local area or there are epidemic prevention and control measures, people will go out less, so there will be relatively few people on the street.
