Is this drawn by hand? How unbelievable it is! Who did it?

    On a street in Nanjing, many people    (停止) in front of a chalk drawing of Dr. Zhong Nanshan. They couldn't help showing surprise. Cong Langui, the artist, sat on the ground and smiled     (甜蜜地).

    For more than    (二十) years, Cong has been drawing on city streets. But this artist is unusual not just because of his chosen “canvas (画布).” When he was 16 years old, Cong lost his left leg because of an    (疾病). With only one leg, life has been hard for Cong, but he has always tried to be brave. He taught    (他自己) to draw by reading books and watching videos.    (从┈┈以来) then, he has gone on to draw art pieces on the streets of many different Chinese (省份).

    Each street drawing takes about six hours to finish. Every now and then, Cong would stand up tocheck his work faraway. He always wants to make it    (完美的). Cong says this is his way of making the city more beautiful.

    We often hear people say that life is    (不公平的). But Cong, a one-legged artist, has never said anything or    (争论) about anything. So next time you want to complain about life, think of Cong.
