5. Zhu Kezhen, my country’s famous meteorologist, has been going outdoors to observe and record the climate every day since he started working in meteorology, and he has done so for decades. Until the day before his death, he used trembling hands to write down the temperature of the day on his hospital bed. Since he could not go outdoors to measure it in person, he relied on the report of the Meteorological Bureau, so he wrote the word "bureau report" on the record. .
He has accumulated more than 40 meteorological diaries through his own personal practice. This is not only his first-hand material for exploring my country's meteorological laws, but also the basis for his achievements.
