Walking in Chiang Mai's Sunday night market, with the various melodies of street artists, reminds me of the past. As China's economy develops, we have built various shopping malls in various cities, and the market representing the agricultural society is fading. This has to disappoint me a little bit of nostalgia. While we have modern, standardized, streamlined shopping centers, we have lost the freedom, interest, bargaining power, intimate trading experience, and more diverse options of traditional markets. The Sunday market in Chiang Mai has no hustle and bustle of some ancient cities in China, and there is no deafening hawking from the store's horn. Here, only the elegant melody of the artist, accompanied by the sound of tourists talking to the store. The skin tone of the countries walk here, orderly, everything seems so harmonious and peaceful. Why do I like the Sunday night market in Chiang Mai? Why? When I walked halfway, I found the answer: here brings back memories of my childhood!
