CHONGQING (CQNEWS) -- An old Chinese proverb says, “Be it scorching hot or freezing cold, we should keep up physical training.” When walking in the Zhenglongsi Park in Duliang New Area in an early morning of summer, you will be greeted by the refreshing greenness and citizens who take exercise or take a stroll in twos or threes. What a good time! The sound of laughter from the children who run and chase with each other, the musical sound of gymnastics and the sound of chirping birds are mixed together to bring vitality to the city park in this summer.
