In May 1928, the Japanese killed indiscriminately in Chinese territory, and Jinan City was horribly sad. At that time, Cai Gong, who was a negotiator, was cut off his ear and nose and shot dead, without showing the slightest cowardice. He faces severe punishment, and he must firmly believe that the Japanese will roll out of our land and we will win. Our current peace is the martyrs with boiling blood, with hot life in exchange, so we should not forget the national shame, strive hard, as long as we firmly believe in the dream of the heart struggle, will definitely succeed.
