二十出頭的小曹曾因為大法申訴而被關在看守所半年，那時正值隆冬。
有天晚上牢霸搶了一個牢友的被子蓋，牢友凍的瑟瑟發抖。小曹馬上把自己的被子給他，自己默默忍受整夜寒冷。
牢裡的人都感動的說法輪功的人真好。他們問小曹：「共產黨這麼強大，你們大法弟子是不是在雞蛋碰石頭？」
小曹說：「每個大法弟子都是一滴水。如果所有大法弟子都勇敢的抵制迫害，我們就能匯成正義的海洋、結束這場邪惡的迫害。」
從那以後一見大法弟子關進來牢友們就喊：「又來了一滴水！」（待續）

Cao, who was in his early twenties, was once detained in a detention center for half a year due to petitioning for Dafa. It was glacial winter then.
One night, the bully of the cell snatched up a cellmate’s covers, leaving the cellmate to quiver with cold. Cao immediately gave his covers to the cellmate, quietly enduring the cold for the whole night.
All of the cellmates were moved and said Falun Gong practitioners were really kindhearted. They asked Cao, “The CCP is so strong. Aren’t you Dafa practitioners fighting a hopeless battle like an egg is fighting against a stone?”
Cao said:
“Every Dafa practitioner is a drop of water. If all the Dafa practitioners courageously resist the persecution, we’ll be able to form a righteous ocean and end this evil persecution.”
Thereafter, whenever a Dafa practitioner was put in the cell, the cellmates would shout, “Here comes another drop of water!”
