The author's grandfather was hospitalized because of intestinal obstruction, the author had to watch from the side, almost every two or three hours grandpa had to go to the toilet, and he had to pay attention to hanging water, so there was no time to code, he didn't sleep last night, he still had to work in vain, and he had time to make up for sleep, this situation would last until the weekend, and the grandfather would be sent home by his father on the weekend, and the hospitalization and surgery fees over there could be reimbursed, and the cost of Dongguan was too great to afford.

So, update next Monday.

I hope you don't blame and thank you very much.
