About a decade ago, I lived in an old urban area that have totally different from the present circumstances. When I studied in elementary school and middle school, there are something such as state-run clocks and watches shops, barber shops, cotton cloth shops, traditional Chinese medicine shops in the streets that near my school. However, memory is a kind of quite strange chemical carrier, particularly, history can be existed because it lies on the memory. Before the photography emerges, there was a little bit illusion that relied on the scenes what the memory had described. For something disappeared, we were difficult to clearly branded every point of every moment in our brain cells.
