昌盛 (chāng shèng) — Flourishing at Scale · A Trade, a Line, an Era on the Rise

One of the earliest surviving uses of 昌 in Chinese poetry means crowded. In 《诗经·齐风·鸡鸣》 a wife is trying to get her husband up and out the door: 东方明矣，朝既昌矣 — the east is light, the court is already 昌. The poem is seven or eight centuries older than the compound, and by the time the two characters had been joined into a word, the commentators were already using each half to gloss the other. The standard Han reading of that 昌 is 盛.

The graph is 日 over 曰 — the sun above the element for speech. China's first dictionary (Shuowen Jiezi, c. 100 CE) gives 美言也, fine words, as its main gloss and 日光也, sunlight, as an alternate, and quotes this same poem as its example. Many paleographers reading the oracle-bone forms take the light as primary — a sun over a mouth-shaped element, brightness first and everything else downstream of it — though the graph has never been settled either way. It hardly matters for the sense. Fine words and sunlight are both things that carry: they are noticed from a distance.

盛 arrives from the other direction, from the table. Its foot is 皿, the vessel radical, and the Shuowen defines it as 黍稷在器中以祀者也, the millet heaped in a dish for an offering: filled past the level, then ample, then at the height. So the compound holds two unlike pictures of abundance. 盛 is the kind that fills — quantity, vigor, a vessel that will not take more. 昌 is the kind that shows. What 昌盛 names is flourishing legible from outside itself, which is why the word has always attached to large and long-running things: a state, an age, a trade, a family line.

• 东方明矣，朝既昌矣。

  《诗经·齐风·鸡鸣》(Book of Songs, "The Cock Crows," c. 9th–7th c. BCE)
  The east is light; the court is already thronged. — A wife pressing her husband to get up and go, in a poem that is mostly him arguing that it is not morning yet. 昌 here is at its plainest and most physical — full, crowded, in full swing — and the standard Han commentary glosses it with one word: 盛, the other half of this compound.

• 俾尔昌而炽，俾尔寿而富。

  《诗经·鲁颂·閟宫》(Book of Songs, "The Solemn Temple," c. 7th c. BCE)
  May you flourish and blaze; may you have long years and plenty. — A temple hymn for the lords of Lu, setting out in ten characters what a state was supposed to want. 昌 leads the list, and the verb it is yoked to — 炽, to burn fiercely — is the measure of how public a thing that flourishing was meant to be.

• 唐虞之际，于斯为盛。

  《论语·泰伯》(The Analects, Book 8, c. 5th–4th c. BCE)
  Since the days of Yao and Shun, there has been no richer time for it than this one. — Confucius on the ten capable ministers King Wu claimed to have, in the same remark where he says 才难, talent is hard to come by. His measure of a flourishing age is not its treasury or its borders but a headcount of who was available to do the work.

Two cities carry the first half of this word in their names, and both were given it on purpose. 武昌 was minted in 221 CE, when Sun Quan moved his seat to a county then called 鄂 and renamed it on a four-character slogan — 以武而昌, flourish by force of arms. 南昌, the provincial capital of Jiangxi, was walled early in the Han and takes its name from 昌大南疆: make the southern frontier flourish. 昌 is the character an administration reaches for when it wants a place to become something, and the compound never came down from that altitude. 繁荣昌盛 is what most people in China hear first from a television — the standard thing said of the country on National Day, printed on banners and read out in speeches.

Knowing that altitude matters before the word is given, because it sets the size of what the recipient hears being wished. Applied to one household's kitchen, 昌盛 lands like a weather forecast read for a continent. Applied to a trade, a firm, or a family line it is exactly right. The distinction that governs it is one of genre rather than scale: the red paper pasted at a shop door each spring says 生意兴隆 because 兴隆 is the couplet formula, while 昌盛 is the register of the toast, the speech, and the plaque — a two-person shop can perfectly well be wished 生意昌盛 on a card. Its close relative 昌隆 is no smaller, and travels just as wide: 国运昌隆 for the fortunes of a state, 家道昌隆 for those of a household. What 昌盛 asks for, in any of these settings, is a span with years in it and a result someone outside can see.
