We ushered in the "spring equinox" solar term
As an equal spring "C position" solar term
How is the equinox determined?
Is it a period of time or a moment?
Why is there a standing egg custom?
This "study note" is now in favorites!
See the solar term! Spring equinox "six feet six inches and six points"
The Kei watch is one of the first timers in the world
As early as the pre-Qin period
The ancients based on the length of the shadow of the sun on the Kei watch
Quantify time
Confirm the twenty-four solar terms
Guijiao measurement findings from the Ancient Observatory in Beijing
The shadow length of the equinox is six feet six inches and six minutes
The shadow length is longest during the winter solstice
It is one foot five feet nine inches
The summer solstice has the shortest shadow length
It is two feet three inches
The ancients were the first to pass the Gui watch for photographs
Confirm the winter solstice and summer solstice
Four times are awarded after a tie
Confirm eight verses in equal divisions
Twenty-four gases were confirmed in three equal parts of each section
It is divided into twelve medium qi and twelve solar terms
Modern times collectively known as the twenty-four solar terms
The vernal equinox also comes from this
When does the equinox arrive? The sun is said to be determined by TA
Through continuous astro-meteorological observations
Later generations compiled observations of the sun into the calendar
It was first adopted in the Constitutional Calendar
The spatial method divides the twenty-four solar terms
Modern astronomy spatially
The ecliptic of the Sun's trajectory is divided into 24 segments
Every 15 degrees of movement of the sun is a solar term
Qi Rui, deputy director of Beijing Planetarium, introduced
When the Sun "walks" to the point where the ecliptic meets the equator
It means entering the vernal equinox moment
The equinox is astronomically a point in time
At the time of the spring equinox
The sun shines directly on the equator
The northern and southern hemispheres receive equal amounts of light and heat
Vernal equinox
The sun rises due east and sets due west
Day and night are divided equally
Standing eggs, eating spring vegetables, and sending spring cows
The equinox turned out to be so interesting
The twenty-four solar terms are Chinese philosophy of time
The spring equinox is approaching and spring ploughing is busy
The equinox is the beginning of warmth
It is also spread among the people
There are many customs such as sending spring cows and eating spring vegetables
But why does the equinox erect eggs?
School of Sociology, Beijing Normal University
Xiao Fang, head of the Department of Anthropology and Folklore, introduced
In fact, eggs can be erected in all seasons
The spring equinox egg embodies the concept of the time when people are in good time
It is a manifestation of harmony between man and nature
Spring has arrived and the flowers have bloomed
May you live up to your long days and run to your love
