What does it mean to fish for three days and cast a net for two days?

Originally it meant five days, three days for fishing and two days for drying fishing nets. This is the best way to fish. Because it is impossible to fish every day and dry the net every day. It is impossible to repair the fishing net when fishing. At present, it refers to the lack of perseverance, frequent interruption and long-term persistence in learning.

Pinyin: sān tiān d m yú, Li m ng tiān shàI w m ng.

Usage: compound sentences; Make provisions; derogatory sense

Explanation: Metaphorically, there is no perseverance in study and work, which is often interrupted and cannot be adhered to for a long time.

Source: Cao Qingxue Qin's Ninth Story of A Dream of Red Mansions: "So, it is also assumed that I will come to school, but I will go fishing for three days and bask in the sun for two days, and give Jia Dairu some free gifts."

Going to school through such comments is just three days of fishing, two days of drying nets, and giving some gifts to Jia Dairu for nothing.

Sentence: Physical exercise should be done every day, instead of fishing for three days and sunbathing for two days.
