He retired to the countryside, enjoyed reading, and had unique views on reading.
he advocates "study hard, but not seek for great understanding".
In the Biography of Mr. Wuliu, I wrote: "Quiet and quiet, don't admire Rong Li. Good at reading, not asking for much understanding. Every time I know something, I will happily forget to eat. "
here, "study hard, don't ask for much understanding" means that although you study hard, you don't give tedious exegesis.
