Why are there so many Chinese people travelling? Because they are heading home for the Chinese New Year. It is the Year of the Rooster.
With regard to the question "Why are there so many Chinese people travelling?", I have to say that it's true that there were lots of Chinese people travelling on 28th January, but there were also hundreds of millions of people from all over the world travelling to China, as this country was getting ready for one of the biggest celebrations in the world: Chinese New Year.
Chinese New Year, which was Saturday 28th January this year, is the Year of the Rooster. This celebration is also known as "The Spring Festival" and it's marked by the lunisolar Chinese Calendar, so the date changes from year to year. Each Chinese New Year is characterised by one of 12 animals which appear in the Chinese zodiac. Accoding to this calendar, 2017 is the Year of the Rooster, the 10th animal in the cycle and it won't be again until 2029. What a long time!
In the Chinese Zodiac Calendar I'm the dragon since I was born in the year 2000. People whose zodiac sign is the dragon are powerful, confident, smart and witty, but lack self-awareness. It is said that we also have a bad temper.
