Guangzhou's bald cypress trees turn red after cold snap

Bald cypress trees in Guangzhou, the capital of Guangdong province, have turned red after cold air swept down from the north over the past week, forming a red line in most parks and wetlands in the city.

The bald cypress, which is native to North America, is noted for the russet-red color of its needle-like leaves, which first turn yellow in autumn, then turn copper red, and finally fall off in the cold of winter.

The changing colors in a bald cypress forest usually last for about one month, presenting one of the country's most beautiful landscapes of the year.
