Mention about the topic, 1980s is the period that I am really interested in. You know, at that time, bicycle was an essential part of our daily life in my country. People who traveled to different places were most likely to ride their own bicycles. More importantly, there wasn't any sorts of air pollution at all doing that special period, as the industrial development was rather slow then. As you probably know, most of the ordinary citizens had slow life, they didn't necessarily have to worry too much about the good job opportunities or living conditions, they were far less likely to suffer from all sorts of pressure psychologically and physically as well. Cuz my dad showed me something one or two on his personal photos, a smile of joy could be easily found on his face. This is really important. I personally found this part quite interesting mainly because of the simple life those people have had. You know, people were usually warm, generous and kind-hearted, not like in today`s society where people become more selfish in general. That is it.
