บท 1502: Big Yu (2)

"Fertilizers?" 

"That's right," Yu Dong nodded as she explained, "Locusts make excellent fertilizers if they are mixed with cow dung and fruit and vegetable waste. Once the fertiliser is done composting we can spread it over the fields and the ground will be even more fertile than the last time." 

"Madam Yu really knows a lot of things, doesn't she? Even though we have been farming for a long time, we had no idea that locusts could be used as fertilizer." 

Yu Dong simply smiled and said, "It's nothing too grand. I just read it in a book while working in the town." 

"Knowing how to read seems to be a really useful thing," said one of the women as she glanced at her daughters. Would they become someone like Yu Dong if she were to send them to school? 

Though Yu Dong did not go to school, she did learn how to read and write from her mother. If a few words could help Yu Dong, then certainly it could help her daughters make a living.
