Almost all the people are concerned about the weather, whether they are school children going to school, peasants going to the fields, workers going to the work, or old people doing morning exercises, or shoppers around the city. Of all the people, farmers care about the weather most. All the year round they want to know the changes of the weather, concerning the temperature, raining or freezing, etc. This is particularly so after farmers have planted seeds, as very big changes will bring them good or bad luck during the harvest.
