Siberian tigers chase and play in the snow fields of the Northeast Siberian Park in Harbin. The northern “Ice City” welcomed its first snow after the Start of Winter on Nov 13, blanketing the entire metropolis. The traditional Chinese lunar calendar divides the year into 24 solar terms. Start of Winter, (Chinese: 立冬), the 19th solar term of the year, begins this year on Nov 8 and ends on Nov 22.
