In the heartland of Northeast China's Heilongjiang province, as the harvest season unfolds, the modern agricultural demonstration field in Fujin city, Heilongjiang, is buzzing with activity.

At the forefront of this agricultural hub, 23-year-old Wang Guotai and three other meteorologists take charge of the agricultural meteorological services, including daily weather monitoring and forecasting.

Their routine involves conducting meteorological observations, regularly collecting samples and maintaining equipment in the vast expanse of the demonstration field. Based on the information they collect, a database is built.
