Aunt Bao smiled.
"Madam, although it's cold in winter, it becomes terribly hot when summer arrives. One can't help but wish to use the ice blocks from winter in the summer!" Every summer is so hot that one sweats all over, and Donglin's Jincheng is even hotter than this small town. Aunt Bao came from Prince Rui Residence in Jincheng, where it feels like being roasted by fire every early morning and evening every year.
Su Yunjin had a sudden inspiration.
It was winter now, a perfect opportunity to store ice blocks. This place is ancient, unlike modern times, where there's air conditioning and refrigerators, so there's no need to store ice blocks from winter.
In ancient times, there was nothing, and Su Yunjin had once seen in a book that people in ancient times had dug ice cellars to store ice blocks, which could be used to cool down during summer.
