The spring rain has just stopped, and Lijia Village is shrouded in hazy water vapor. In the dilapidated thatched house at the east end of the village, 16-year-old Lin Xiu frowned and looked at the bottomed rice vat. There was only a thin layer of brown rice left, which could not be made into porridge for more than two days. "Sister, I'm hungry." Her five-year-old brother Xiaobao tugged at the corner of her clothes. His face was so thin that only a pair of big eyes remained. Lin Xiu touched her brother's head, feeling sad. Three months ago, their parents died of illness, leaving behind their siblings and a pile of debts. In order to pay off the debt, everything the family could sell was sold, and now they are really impoverished.
