Tragic Execution: Kindergarten Teacher's Disturbing Descent into Madness 

Kindergarten Teacher Executed: A Chinese teacher, Wang Yun, was executed for poisoning students with a harmful substance, resulting in one child's death.

Motive Behind the Poisoning: Wang mixed sodium nitrite into the children's food after an argument with a colleague. Sodium nitrite can harm red blood cells and oxygen transport.

Tragic Consequences: While most students recovered, one child suffered organ failure and died after months of treatment. Others sustained minor injuries.

Legal Proceedings: Wang was initially sentenced to nine months in prison but later received the death penalty. Her appeal was rejected, leading to her execution.

Concerns Over Child Safety: Wang's case is among several incidents of violence or deaths in Chinese kindergartens, raising concerns about the safety of children at school.
