Over the past few days, large parts of northern China have experienced a sharp fall in temperature.

As a new wave of cold air hit Northeast China's Jilin Province, residents saw the biggest drop this autumn, with some areas falling more than 10 degrees Celsius. Health officials are warning people to keep warm.

In Liaoning Province, heavy rains and strong winds have battered the area since Monday morning, prompting authorities to issue a storm alert. The rains helped bring temperatures in the provincial capital Shenyang down to 18 degrees from a high of 25.

Further west, residents in China's Gansu Province have already brought out their autumn clothes as temperatures dropped 6 degrees Celsius since this week. The sudden drop was also seen in North China's Shandong Province. Temperatures dropped to 16 degrees Celsius in the city of Zibo and is expected to fall to 10 degrees by Wednesday.
