To be precise, the call from Tao Ye was intended for Grandpa Lu's help, but it was answered by Lu Qingqing.
Before high school, under the influence of her elders, Lu Qingqing, though young, had an easily overflowing sense of compassion. She thought it very pitiable for someone not to be able to afford schooling or food. Although she earned some income from writing, it was sporadic, so she only occasionally donated money on a whim to do good deeds.
Unlike Grandpa Lu, Grandma Lu, and Maternal Grandma and Maternal Grandpa, who had persisted for decades. Apart from the students they actively sponsored, there were also those who sought their help.
Tao Ye was one who sought help on his own initiative.
