The tale goes that Le Loi King came across a shining metal bar when he visited his friend. It turned out that his friend caught the bar in one of his attempts for fish. The King asked for the bar, brought it home and moulded it into a sword. All of a sudden, there was two words printed on the sword “Thuan Thien” (harmonious with heaven). Le Loi then understood that the sword was a gift from heaven. He used it for the battle against the war with a neighbouring country. At the beginning of 1428, when peace prevailed, on one of his trip to the Thuy Quan (now Hoan Kiem) Lake, there was a tortoise rising above water and shouting: “Please return the sword to the Dragon King”. Without hesitation, the King threw the sword to the lake. The tortoise took the sword and dove down the water. From then on, Thuy Quan became Hoan Kiem lake.

Located in the middle of Ha Noi, a rapidly developing city where changes take place every hour, Ha Noi Old Quarter with its old-styled narrow streets full of antique brick houses seems to nostalgically resist the flow of time while still actively trying to adapt to the dynamic atmosphere of the modern city. Once a bustling area where merchants and artisans gathered to sell their products, Ha Noi Old Quarter consists of many small, meandering streets, each bears the name of the goods that was specifically traded there such as Hang Bac (Silver Product), Hang Ma (Paper Product), Hang Go (Wood Product), just to name a few. Visiting this unique historical vestige comfortably lying around Hoan Kiem Lake, tourists get lost in a totally different world from the rest of the city and have the chance to explore the modest but energetic life of the local a hundred years ago, where there were no high-rise buildings, too much traffic or fancy stores; things will get a little bit smaller, as visitors may have used to those skyscrapers and shopping centers in other parts of the city, but not at all less lively and vigorous.
