Jiao Yulu, secretary of CPC Lankao County Committee, stands in front of a Kiri tree in this undated photo. Jiao, dying of liver cancer at age of 42 in the year of 1962, is always considered as one of the model examples of CPC servants because he was dedicated to fighting against flood, sandstorm and other natural disasters in central China’s Henan Province in the middle age of last century.
