(For those of you who do not know where Harbin is, it is located in the Heilongjiang province of China. In short, it is situated at the north-eastern part of China. You could say it is Russia's neighbour! This would explain its Russian influence on its architecture and food (yes, you get to eat Russian food here!).
I was there during its winter and I must say, it is really an eye-opener for me considering I live in a tropical climate. Winter in Harbin is bittersweet because it is cold with snow and ice but yet it is too cold! But my advice is to dress warm and you will be able to embrace its winter :)
Harbin is known for its annual Snow and Ice Festival which typically starts at the beginning of January. Do note that the dates are not fixed each year as it depends on the temperature and the condition of its ice and snow sculptures.
But fret not, if winter is not your thing, you can still visit Harbin during its other seasons as there are still things to see!
