[citation needed] 章 combines the characters 音 (yin, "sound", "(musical) note") and 十 (shi, "ten").
It originally meant "brilliant", "to display", "a distinctive mark"[2] and was used as the name of a fief, but as a common noun in modern use it means an "article" in a newspaper or magazine or a "chapter" in a book or law.
On the establishment of the state of Qi, Jiang Ziya apportioned the land among his many descendants, including a one known as Zhang (鄣国).
Some of the people of this state simplified the character and took 章 as their surname, particularly after it was annexed by Qi.
[3][full citation needed] The Middle Chinese pronunciation of the name was Tsyang, the beginnings of what we now know to be the "Zhang" surname.
