During the period of 1979, Shanghai Font Factory invited national famous calligraphers to try writing in order to fill the blank of movable type typesetting in newspapers and magazines. At that time, more than 40 calligraphers took part in the competition. The author's name is hidden in the work, and readers' opinions are widely sought. After judging and voting, Ren Zhengxing's book "Casting a Hundred Schools, Wonderful Integration" won the bid in one fell swoop. Since then, Ren Zhengquan has been adopted by major newspapers and CCTV. Later, as a "writing standard model", it entered the national standard computer font and penetrated into thousands of households.
