At the age of seven, the fun Valentine's Day received a relic from a soldier's father-a handkerchief with his birthday printed on it. The soldier told Farney that his father was captured by the enemy and tortured in prison, but he never answered any information. In order to find some clues from him, the enemy searched every corner of him and found nothing. Farney asked the soldier, "Where did father hide the handkerchief?" The soldier told Farney that his father had been blind in his left eye long before he was examined, so he endured the pain and dug out his blind left eye, rolled the handkerchief into a ball and saved it.
