What pictures would come to your mind first about China's spring? Or are you tired of blossoming flowers ?

Due to geographic and climate differences across China, spring actually has a variety of signs with unique local traits.

Here are some unusual spring scenes you might have missed this year.

#Spring Tea

April is the busy time for tea farmers to harvest spring tea. In the picture above, people are collecting fresh tea leaves in a farm in southwest China's Guizhou Province last week.

Here is a closeup on fresh Wujiatai tea leaves at a tea garden in central China's Hubei Province.

#Baby Lambs

Spring also marks a season for lamb births in high altitude region. Tibetan sheep, which mainly live above the elevation of 4,500 meters, are the essential means of livelihood for local herdsmen.

In the picture taken at the Sensen Spring Pasture in Qiaga Township of Damxung County, southwest China's Tibet Autonomous Region, can you tell which of the ewes are pregnant?

Here comes another newly-born lamb picture taken by Xinhua photographer Chogo.

#Ice & Snow

While most part of south and east China has become quite warm, the northwestern part of the country remains cold.

A snow hit northwest China's Qinghai Province in late March, attracting many locals to take pictures of the white spring. A cutie snowman was under the spotlight in Xining, capital of Qinghai on March 24.

Actually, the whole province was still cold at that time.

The Qinghai Lake, China's largest inland salt lake, begins to melt in spring. The above is a picture of melting ice on the surface of the lake on March 20.

Partially covered by snow on March 9, the landmark Hukou Waterfall of the Yellow River is a must-go place for many tourists in north China's Shanxi Province.

Floating ice still blanketed part of the section of the icy Yellow River on March 13 in the Gudengkou County, north China's Inner Mongolia Autonomous Region.

#Migrating bird

With the big contrast of climate, many migratory birds just travel within China to spend the winter.

Above is a photo taken on Feb. 25, when a flock of pied avocets were preparing to fly back to the north from the East Dongting Lake National Nature Reserve, their winter habitat in central China.

More than 120,000 birds were estimated to have spent the last winter in that region.

Last but not least. Some 2,000 km away from the Dongting Lake, flocks of migratory birds formed the shape of a huge bird in the sky over the wetlands of the Yalu River in northeast China's Liaoning Province on April 4, 2016.
