The longest day of the year夏至这天白昼最长
On the Summer Solstice itself, daylight lasts the longest for the whole year in the northern hemisphere. After this day, daylight hours get shorter and shorter and temperatures become higher in the northern hemisphere.

According to the expert Yan Jiarong, the entire day in Mohe in Heilongjiang province, located in the northernmost tip of China, lasts nearly 17 hours when you include dawn, twilight and its afterglow. Summer Solstice is the best season for viewing the aurora in Mohe, "the sleepless town of China".

在中国古代，夏至是一个很重要的节日。早在汉朝时期（公元前260年-公元220年），中秋和重阳还没有像现在那么重要的时候，就已经在庆祝夏至了。
Before the Qing Dynasty (1644-1911), people even had a one-day holiday on Summer Solstice. According to Song Dynasty (960-1279) records, officials could have three days off during the Summer Solstice.
清朝（1644年-1911年）以前，人们甚至会在夏至这天放一天假。根据宋朝（960年-1279年）文献的记录，官员在夏至可以放三天假。
To celebrate Summer Solstice, women gave colored fans and sachets to each other. Fans could help them cool down and the sachets could drive away mosquitoes and make them smell sweet.

Hani autonomous county of Mojiang, Southwest China's Yunnan province is located on the northern tropic. Every year on the Summer Solstice, the sun sits directly over the Tropic of Cancer and returns from north to south. Then, the amazing phenomenon known as "upright pole with no shadows" occurs.
云南省墨江哈尼族自治县位于北回归线上。每年夏至，太阳会直射北回归线，而后太阳直射点将从北半球逐渐南移至南半球。此时就会出现“立竿不见影”的奇观。

据东汉时期（公元25年-220年）应劭的《风俗通》记载，一位名叫杜宣的男子在夏至这天参加了一场宴会，他将映入酒杯中的弓影误以为是蛇，但因畏惧主人不敢不饮下这杯酒。
