1890, Zhu Kezhen was born in Dongguan Town, outside the East Gate of Shaoxing, Zhejiang. His father wanted his son to be a dragon, so he asked someone to give him a scientific name "Ke Zhen", which means that he will become a pillar of the country in the future.

When Zhu Kezhen/Kloc-0 was 0 years old, his father began to teach him to read and recite poems. When he was five years old, his father asked him to go to school. He studied very hard since he was a child. He studies late every day and gets up to study when he hears the cock crow. His mother is afraid that she will be exhausted, so she often helps him recite his studies by accompanying him and tells her to go to bed early.

Zhu Kezhen not only studies hard, but also likes thinking very much. One day, while he was studying, it began to rain lightly. He watched the rain dripping down the eaves on the bluestone board, leaving a row of small puddles. He was very curious, so he slowly pondered and pondered. Suddenly, he remembered the famous saying of the ancients in the book, "A drop of water wears away a stone", and he understood the truth. A drop of water is nothing, but over time, it becomes a hard stone.
