The meaning, explanation and origin of spring cold.

"Spring is chilly, but at first glance it is still cold" is a sentence to describe the changeable temperature in spring. Although the weather has warmed up in spring, it is still chilly and unpredictable, so people need to pay special attention to keep warm.

The origin of "chilly spring, suddenly warm and cold" is complicated, which may be composed of multiple documents. Among them, Yuan Chuanzhong's "chilly spring, continuous snow" and Xu Shiqi's "suddenly warm and cold" have certain influence. There is also a record in the Biography of Ma Yuan in the Later Han Dynasty that it is warm in winter and sometimes cold. These documents have gradually evolved into idioms that are widely circulated today through the inheritance of time.
