Traffic in Hanoi is chaotic, but the public security is still good. I have been out to take a taxi after midnight a few times and nothing happened. And I haven't heard of any fights, murders or arson in such a long time.
There are many foreigners in Hanoi. If you walk around Hoan Kiem Lake at night, you will find many languages (English, Chinese, Korean, Japanese, etc.). It is a romantic place, and there are many Vietnamese couples snuggling on the stone benches by the lake. It is a harmonious scene, so Vietnamese people are not xenophobic.
From January to October 2024, Hanoi reported international tourist arrival numbers at 4.95 million-the highest record among all provinces of Vietnam, with a growth of 36% year- on-year, thus achieving almost 99% of the annual target in1978. As per reports, in the first half of 2024, 3.14 million foreigners traveled to Hanoi, representing an increase of 52.6% over the previous year. These statistics therefore point to a remarkable number of foreign visitors to Hanoi, the capital of Vietnam.
