The tour guide A Shan led us to the 36 blocks of Old Town near Huanjianhu, where there are old-fashioned commercial streets with houses facing the streets. It is said that these streets are named after the names of goods traded centrally, such as "Cotton Street", "Paper Street", "Sailing Street", "Yulu Street", "Silver Street", "Xihang Street", "Tea Street" and so on. With the development of the times, many street names are still used, so many European and American tourists come to Hanoi here is also a must-come place. And we tourists from China, see these small streets, in addition to feeling crowded almost no novelty, after all, there are more such commercial streets in China. We walked three small streets and soon returned to Huanjian Lake. It was the natural scenery here that attracted us more.
