reported year-on-year expansion in operating revenue.

Total operating revenue of the 16 subcategories closely related to new business forms, such as animation, games, and digital publishing, climbed 18.9 percent year on year. It accounted for 33.3 percent of total revenue of the culture industry.

Zhang expected further expansion of China’s culture industry in 2022, highlighting the supply of higher quality products and the dynamic consumption market. built and the charm of Chinese culture will be presented to the world through a host of cultural resorts, parks and brands.

The plan specifies efforts to promote and popularize winter sports among the general public, increase the venues’ public accessibility and improve their services, and facilitate the wider spread of Winter Olympics culture.

A Chinese quartet stormed to a thrilling victory in the mixed 2,000m relay at the Beijing Winter Olympics on February 5, clinching China’s first-ever gold in the event. The feat can be partly attributed to aviation technologies.

A research team led by Ke Peng, an associate professor at Beihang University in Beijing who once studied air vehicles, has applied the knowhow of aircraft engineering into winter sports training.

The endeavor can be traced back to a chilly morning when Ke went to a skating rink in suburban Beijing. There, Ke’s team collected data via multiple sensors based on the athletes’ movements, muscle strength and details involving the skate blades.

Later it occurred to Ke that the route planning algorithms used for aircraft could also be used to help design optimal glide routes for skaters.

Ke pondered over some critical questions such as whether or not skaters should slow down before they turn and whether they should turn in a small circle or a large one, concluding that the model can offer the answers.

The model is tailored to individual skaters. Inputting their heights, gliding postures, muscle energy consumption, angles of arm swings and leg kicks into the model can produce the optimal plan for energy distribution.

“Thanks to the scientific training approach, a typical speed skating race saw a 10-percent increase in speed,” Ke said.
