Brief Introduction

Hanlu 寒露 is the 17th of the 24 Solar Terms二十四节气.It begins when the Sun reaches the celestial longitude of 195° and ends when it reaches the longitude of 210°. At this time, temperatures are much lower than during White Dew in most areas of China. The dew is greater and colder and there will be less rain. Autumn crops will be ripe.

Temperatures drop significantly in October. When the cold air encounters autumn rain, the abundant water vapor in the air soon reaches saturation, and then it turns into misty rain or fog. When the humidity is high, there will be foggy regions formed in many areas of China.

People always say that fishing in shallow water in autumn makes sense. That’s because during the Cold Dew period, temperatures decrease quickly and sunshine doesn’t reach deep water thoroughly. Fish swim to shallow water areas where the water temperature is relatively high.

Pomegranates are ripe during Cold Dew. Pomegranates have been cherished for their exquisite beauty, flavor, color, and health benefits for centuries.

Drinking chrysanthemum wine 喝菊花酒

According to ancient records, drinking wine made with chrysanthemums, poria, cocos, mushrooms and pine oleoresin grants people long-lasting youth.

Appreciation of Maple leaf 欣赏枫叶

During the Hanlu, many places have the custom of viewing maple leaves. “Maple leaves are redder than February spring flowers” is also said during this season. The word “appreciation” for viewing maple leaves is very important. It is different from sitting on the windowsill or walking down the street to look at the leaves.
