3. Ha Noi is a beautiful and poetic city.I want to visit Ha Noi because it has 36 famous street,each representing a unique craft village. The people here are elegant, open, and friendly. Attractive tourist destinations such as Bat Trang pottery village, the Temple of Literature, and the Ho Chi Minh Mausoleum are all steeped in the city's long history. In addition, local specialties like Vong sticky rice cakes and Trang Tien ice cream are also very appealing. Ha Long Bay is also a great choice with its many islands and historical caves, where you can enjoy delicious seafood.
