Beijing unveiled the design of the medals for the 2022 Winter Olympic Games on Tuesday, exactly 100 days before the Games 
begin. Named "Tongxin", meaning "Together as one", the medals feature five concentric rings embodying the traditional Chinese 
philosophy of harmony between heaven, earth and humanity
The rings also symbolize the Olympic rings, carved in the inner circle, and the Olympic spirit uniting the world through sport.
The surrounding grooved rings are engraved with the Games' official title, "XXIV Olympic Winter Games Beijing 2022," along with
 cloud and snowflake patterns.
The reverse side has the Beijing 2022 emblem at its heart, with the official name of the Games carved in Chinese below.
The surrounding rings mimic star trails, with 24 dots representing the 24th edition of the Winter Games.

kilometers.

Myopia rate falls by 0.9%
The prevalence of myopia among Chinese children and teenagers was 52.7% in 2020, a decrease of 0.9 percentage points from 
2018, the Ministry of Education said Tuesday. The myopia rate in 2020 was 2.5 percentage points higher than the 2019 level, 
as schools shifted classes online and students had to study at home due to the COVID-19 epidemic. According to the ministry, 
this decline has basically met the annual target of reducing the myopia rate by 0.5 percentage points stipulated in a 2018 plan.

Jordan's sneakers sell for nearly $1.5M
A pair of sneakers worn by NBA superstar Michael Jordan early in his career sold for nearly $1.5 million on Sunday, setting a
 record price at auction for game-worn footwear, Sotheby's said.
"The most valuable sneakers ever offered at auction — Michael Jordan's regular season game-worn Nike Air Ships from 1984—
 have just sold at $1,472,000 at our luxury sale in Las Vegas," the auction house said in a statement on Twitter.
The astronomical price easily beat the record held by a pair of Nike Air Jordans which sold for $615,000 in August 2020 at a 
Christie's auction.
Jordan is seen by many as the best player in the history of basketball.
Jordan, who retired in 2003, also became the first billionaire player in NBA history.
