Why 谷雨 Is Chinese Language Day: Cangjie, Characters & the 汉字 on This Site

Every year on April 20 — the date of the solar term 谷雨 (Gǔyǔ, Grain Rain) — the United Nations marks Chinese Language Day. It is one of six UN language days, and unlike the others, it is tied not to a political date but to a legend: the story of 仓颉 (Cāngjié), the mythical figure said to have created Chinese characters.

If you have read any article on this site, you have encountered 汉字 (hànzì) — Chinese characters — alongside their pinyin romanization and English translations. Terms like 风水, 气, 阴阳, 五行 are not decorations. They are the original language of the tradition we are exploring, and each character carries layers of meaning that an English translation can only approximate.

Today, I want to tell you the Cangjie story, show you how a few of the characters we use most are actually built, and share why — in Chinese tradition — the written word has always been considered something worthy of respect and careful placement in the home.

The Legend of Cangjie

According to tradition, 仓颉 (Cāngjié) was a court historian serving the Yellow Emperor (黄帝, Huángdì), the legendary ancestor of Chinese civilization. The story is told in several ancient texts, with details varying, but the core narrative is consistent.

Cangjie is described as having four eyes — a poetic way of saying he saw the world with extraordinary perception. His task was to record events and knowledge, but the existing system of knots and notches was inadequate. So he observed the natural world: the tracks of birds and animals, the patterns of stars, the shapes of mountains and rivers, the markings on turtle shells. From these observations, he is said to have distilled the first set of written characters.

The legend's most dramatic moment comes when the characters were completed. According to the 淮南子 (Huáinánzǐ), a Han-dynasty text, heaven rained grain and ghosts wailed through the night — heaven was celebrating the achievement, and the ghosts feared that humans, armed with writing, would now be able to record their deeds and hold them accountable.

The connection to 谷雨 is in that rain of grain: 谷 means grain, 雨 means rain. The UN chose this solar term as Chinese Language Day in 2010 to honor the mythic connection between the birth of writing and the nourishing rain.

How Characters Are Built

Chinese characters are not random squiggles. They follow logical construction principles that have been categorized since the Han dynasty. Understanding even a few of these principles makes the characters on this site come alive.

Pictographs (象形, xiàngxíng)

The simplest characters began as pictures. Over thousands of years they became more abstract, but the visual origin is often still visible:

• 日 (rì) — sun. Originally a circle with a dot in the center. The dot became a line.
• 月 (yuè) — moon. Originally a crescent shape.
• 山 (shān) — mountain. Three peaks.
• 水 (shuǐ) — water. Flowing lines representing a stream.
• 木 (mù) — wood/tree. A tree with branches above and roots below.

Compound ideographs (会意, huìyì)

Two or more elements combined to create a new meaning:

• 林 (lín) — two trees (木木) = a grove or forest.
• 森 (sēn) — three trees (木木木) = dense forest.
• 明 (míng) — sun (日) + moon (月) = brightness, clarity. This is the 明 in 明前茶 and the term that gives 清明 (Qingming) its name.
• 休 (xiū) — a person (人) leaning against a tree (木) = rest.

Semantic-phonetic compounds (形声, xíngshēng)

The majority of characters combine a meaning component (radical) with a sound component. For example:

• 河 (hé) — river. Left side: 氵(water radical, from 水). Right side: 可 (kě) gives the approximate sound.
• 妈 (mā) — mother. Left side: 女 (woman radical). Right side: 马 (mǎ, horse) gives the sound.

The Characters on This Site

Here are some of the characters you encounter most often on this blog and what they reveal about the concepts behind them:

Why We Pair 汉字 With Pinyin

Every time a Chinese term appears on this site, I include three things: the characters (汉字), the pinyin romanization (with tone marks), and an English translation. For example: 脾 (pí) — the Spleen system.

This is deliberate. The characters connect you to the original tradition. The pinyin lets you pronounce the term and recognize it in conversation or when you visit a TCM practitioner. The English gives you the meaning. Together, they form a bridge between two languages and two worldviews.

If you find yourself remembering the pinyin for terms like qì, fēngshuǐ, or yīn yáng, you are already building a foundation for deeper understanding. You do not need to read Chinese to appreciate the tradition — but recognizing a few key characters enriches the experience enormously.

Written Characters at Home: Feng Shui of the Word

In Chinese tradition, the written word carries significance beyond its meaning. Calligraphy is considered a high art, and the placement of written characters in the home is treated with intention and respect.

福 (fú) — upright or inverted?

The character 福 (blessing) is one of the most common decorations in Chinese homes, especially during Chinese New Year. A longstanding custom is to hang 福 upside down on certain doors, because 倒 (dào, inverted) sounds like 到 (dào, to arrive) — so an inverted 福 symbolizes "blessings have arrived." However, traditional practice distinguishes between locations: 福 is typically hung upside down on storage rooms, water containers, or interior doors, while the main entrance 福 is displayed upright, showing respect to the character and the blessings entering the home.

Spring couplets (春联, chūnlián)

During Chinese New Year, vertical scrolls with poetic couplets are placed on either side of the front door. The right scroll (facing the door from outside) carries the first line, the left carries the second, and a horizontal banner goes above. These couplets are not just decoration — they are written wishes for the coming year, chosen carefully for meaning, balance, and calligraphic beauty.

Calligraphy placement

If you hang Chinese calligraphy in your home, traditional placement guidelines suggest:

• Living room: Inspirational phrases, landscape poetry, or single powerful characters like 和 (hé, harmony) or 静 (jìng, tranquility). Our wall art guide covers positioning by sector.
• Study or office: 学 (xué, study), 志 (zhì, aspiration), or classical poems about perseverance.
• Bedroom: Keep calligraphy gentle and peaceful. Avoid intense or aggressive characters.
• Not in the bathroom or kitchen: Traditional practice considers these locations disrespectful for calligraphy.

The feng shui symbols guide covers broader placement rules for decorative items, including how to read the intent behind different traditional symbols.

Try It: Characters to Know

If Chinese Language Day inspires you to learn a few characters, start with these — they appear throughout this site and in everyday Chinese culture:

You do not need to write them beautifully. You do not need to memorize stroke order. Just recognizing them when you see them — on a restaurant menu, a tea package, a calligraphy scroll, or right here on this blog — is enough to deepen your connection to the traditions we explore together.

Happy Chinese Language Day. And next time you see a 汉字 on this site, take a moment to look at its shape. Cangjie — legend or not — was right about one thing: the patterns of the natural world have a lot to teach us, if we look carefully enough.
