Recently, Zhang Haimei, a native of Lintao County, Dingxi City, Gansu Province, returned home from a business trip for a few months and unexpectedly received "homework" from her father.

Zhang Haimei said that her father had suffered from cerebral infarction and did not like playing cards and chess, so he stayed at home on weekdays.

Half a year ago, she had to leave home due to work. She only worried that her father would “have nothing to do and get Alzheimer’s easily”, so she joked and assigned the “homework” of “one page of Chinese characters and numbers a day”. She didn’t expect her father to actually complete it. "Doing homework avoids dementia, makes children less troublesome, and has more energy and peace of mind to work." "Daughter-in-law" Zhang Haimei is warm and touched, thinking "the father is as old as a child".
