Anti-Japanese heroes refer to a group of young heroes who emerged in China during the War of Resistance against Japanese Aggression period, such as wang pu, Zhang Ga, Hai Wa and others. After the victory of the Anti-Japanese War, they were all awarded the title of "Young Anti-Japanese Heroes". At the moment of national peril, these teenagers, together with their parents, shouldered the heavy responsibility of the war of resistance with tender shoulders.

During the War of Resistance against Japanese Aggression period, Wang Erxiao's hometown was an anti-Japanese base of the Eighth Route Army, which was often "swept" by Japanese devils. Wang Erxiao is a member of the Children's Alliance. He often stands guard for the Eighth Route Army when grazing cattle on the hillside. 1942 10 10/25 (September of the lunar calendar 16), the Japanese came to "mop up" again and got lost when they reached the mountain pass. The enemy saw Wang Erxiao herding cattle on the hillside and asked him to lead the way. Wang Erxiao pretended to obey and went ahead. In order to defend the villagers in hiding, he led the enemy into the ambush circle of the Eighth Route Army.

Suddenly, gunshots rang out in all directions. Knowing that the enemy had been cheated, he angrily killed Wang Erxiao with a bayonet and threw him heavily on a stone. Just then, the Eighth Route Army rushed down from the mountain and wiped out all the enemies. After Wang Erxiao's death, local soldiers and civilians buried him on the hillside of Liujiazhuang. At that time, Comrade Zhang Shikui, a cadre of Laiyuan Youth Rescue Committee (now a retired cadre in Baoding), got the news and immediately reported it to the Youth Rescue Committee in the Border Region. According to this report, Fang Bing, a poet, and Fu Jie, a songwriter, immediately wrote the song "Sing for two hours and let the Cowherd go". This song has been sung to this day and has infected countless teenagers.

Now, Wang Erxiao's grave is covered with grass. The big stone dyed red by his blood still lies quietly in the ravine. People call it "the bloody stone". To commemorate the little hero Wang Erxiao, the China Youth Foundation established the Hope Primary School of the Second Primary School in Shangzhuang Village, Laiyuan County, the hometown of the second primary school. Chen Mo, an old writer who participated in the revolution in Yan 'an period, created the revolutionary traditional documentary novel "Young Hero Wang Erxiao".
