As temperature in east China’s Jinan, Shandong Province, has dropped to around minus 10 degrees Celcius this week, an elderly who practices calligraphy in a park couldn’t help but write “cold cold freezing cold…” in Mandarin. /VCG Photo

In China, many elderly take a giant Chinese calligraphic brush pen and a bucket of water to the park, and practice writing on the ground as a mental and physical work out. /VCG photo

It is quite an eco-friendly approach using water and ground instead of ink and paper. /VCG Photo

Usually they write poems or inscriptions from the past. /VCG photo

But as northern China freezes, the elderly who work out around the Daming Lake simply wrote in Mandarin: “Cold, Freezing Cold, Work Out and Be Strong, Cold….” /VCG Photo

And this frozen lake shows how cold it must be there. /VCG Photo
