When the Summer Solstice arrived, cicadas began to chirp joyfully.
夏至时节到了,知了开始欢快的鸣叫
The Summer Solstice marks the longest day in the Northern Hemisphere.
夏至迎来北半球白昼最长的一天
Sunlight will become extraordinarily bright, like plenty of sharp arrows striking the earth.
太阳光变得格外明亮,像支支利箭射向大地
Even the ground seems to be melting.
大地感觉都要被晒化了
Ancient people more than 3,000 years ago used Tugui (a kind of measuring tool) to measure the shadow of the sun.
三千多年前的古人用土圭测量日影
They found that the sun was highest at noon on this day, and Tugui's shadow was the shortest.
发现这一天正午太阳最高,土圭的影子最短
The Summer Solstice is the earliest established solar term.
夏至是最早被确定的节气
