Home, will mean and form words. The Shuo Wen: "home, residence. From the 宀, _ provincial sound." Also said: "_", oyster also. This statement is well founded. In the oracle bones of the Shang Dynasty, there are two ways of writing "家", one is "宀"(the pictogram for "宀"), the boar in "宀"(the pictogram for "房屋"), which is a male one (the abdomen has a protruding male genital), and the other is a simpler way, which doesn't emphasize the gender, and highlights the male genitals. Another simpler way to write "豕" without emphasizing the gender and highlighting the male genitalia is to write "_", which is a pictogram of "_", which is also a phonetic symbol. The "豕", which does not emphasize gender, is a provincial form. In the Jinwen of the Zhou Dynasty, the gender-neutral writing style dominated, and the later character "家" evolved from this style. In the Shang Dynasty oracle bones, most of the "boars" in "家" are drawn with the outline of the pig's body, and there are also some that only draw the lines of the pig's body, and the "家" in the Zhou Dynasty Jinwen is evolved from this simple writing style. The Zhou Jinwen "Jia" evolved from this simple writing style. In the oracle bone inscriptions, the strokes of the front hooves of the boar were omitted, but the Zhou Jinwen was evolved from the complete writing style of the oracle bone inscriptions. In addition, in the Zhou Dynasty Jinwen, the original "boar" is like the pig's hind hooves and pig's tail strokes are connected to a single stroke, until the Western Han Dynasty Scribe only divided into two strokes, to the Eastern Han Dynasty Scribe is divided into three strokes, writing is more convenient.
