The old man photographed the sky for seven years in a row. What makes him so persistent?

Recently, there was a news that caught the attention of netizens, that is, there was an old man who kept shooting the sky in his hometown for seven years. It hasn't stopped for seven years. Some netizens are curious, why can they shoot the sky so persistently? I think, firstly, because the elderly love photography, secondly, they care more about the weather and air quality, and most importantly, they love their hometown very much and want to do something for it.

The cause of the matter is this. There was a time when a word called smog was popular on the Internet, and many places were criticized. The air quality is not good, and there is smog in Shijiazhuang, Hebei Province, which was once criticized. The old man comes from Shijiazhuang, Hebei. After he learned the news, he had an idea to take a picture of the sky every day and record the changes in air quality in Shijiazhuang, Hebei Province in recent years. With this idea, the old man began to implement it.

For more than seven years, I have photographed the sky on my balcony every day. Now the old man has made so many photos into histograms, so that netizens can see that the air quality in their hometown is getting better and better. It is not easy to persist in doing one thing for seven years. Why can old people do it? I think first of all, this is his hobby. Secondly, he has a firm goal in doing so, that is, to let netizens see that the air quality is getting better and better, and to record the air by riding.

The deep reason for this is that the old people actually love their hometown and want to do something for it, so they came up with this idea. This is very touching. Everyone can contribute to his hometown. This contribution is big or small, but every contribution can not be ignored. This move of the old man lasted for seven years, which can be said to be very difficult and worthy of our study and praise.
