The world-famous travel site TripAdvisor has just announced the 25 most popular destinations in Asia in 2022. In which, Hanoi was ranked 13th. The city was introduced as a friendly, modern destination, but still preserved its long-standing cultural values. One of the points that create the friendliness of Hanoi is the shade of green trees here. Visitors who have the opportunity to come to the city all are impressed with the city's green system. As soon as visitors get off Noi Bai airport, they will be welcomed with a green and modern road named after General Vo Nguyen Giap. Going deep into the city center, big or small streets are all lined with trees. Many roads in the old town have their typical trees. For example, Phan Dinh Phung street has a long row of ancient dracontomelon trees with thick green foliage. Or the Lo Duc street with tens of meters tall golden oak trees, some even surpassing high-rise buildings. Moving on the streets of Hanoi under the shade of green trees, people can feel the fresh air and don't mind much about the noise, dust, and congestion problems in the city. The green color also appears in various parks, most notably Bach Thao Park. It looks like a tropical forest in the heart of the city, which gathers many types of trees from all over the country. Green trees, especially old trees, also create the ancient sanctity of the thousand-year-old city. It leaves a special mark in the hearts of tourists every time they come to the capital. Along with the Government's goal of planting 1 billion trees, Hanoi wants to plant about half a million new trees of all kinds in 2022. This is an effort of the whole city for the comprehensive development for today and in the future./.
