An iconic building in the middle of Hoan Kiem Lake, an ancient small tower. Back to the hot Hanoi, when eating rice noodles, pointing to the map and asking the store, after arguing the position, I knew that it was not far from Hoan Kiem Lake, so I gave up the store’s suggestion to ask me to take the bus, and walked on foot and watched the opera houses, museums and other tall buildings along the way. Elegant representative French architecture. At noon, return to Hoan Kiem Lake under the sun, and walk, sit, chat, read or think in a leisurely manner under the dense shade of trees.
