Alcohol is an organic solvent that can remove ordinary ink, especially this low-quality ink used for changing production dates!
In the past, there was a dishonest vendor from outside the village who used this method to turn expired snacks into current ones, and then sold them cheaply at the school gate.
He even hired Chen Erniu to help him, thinking the fool would not disclose his secrets.
However, the vendor did not expect that after Chen Erniu returned home, under He Hongjuan's questioning, he gradually revealed what he had been doing.
Learning that the unscrupulous vendor was harming schoolchildren, He Hongjuan was furiously enraged and immediately took Zhang Ling and other villagers to the vendor's home.
With his misdeeds exposed, the dishonest vendor was beaten up by the villagers and then driven out of the village.
But Chen Erniu remembered the method of changing production dates very clearly.
