于氏圖騰釋義 

【釋義】 在古文字中，「于」即「於」，「于」亦即「烏」。古時「呼」與「吁」、「乎」與「于」字形相近，意義也相同。《說文解字》記載：「于，於也，象氣之舒于。」意指氣體舒展的樣子。又解釋「烏」字為：「烏，孝鳥也，象形。」

【起源】 西周初年的大分封中，周武王姬發的次子被封在商代「邘」國的舊址（故城在今河南沁陽邘邰村），稱為邘叔，並建立邘國。邘叔的子孫以國名為氏，姓「邘」。因古代「邘」與「于」同音通用，後來有的後代去掉了「邑」字旁（阝），改為「于」氏。

Interpretation of the Yu Clan Totem 

[Definition] In ancient Chinese scripts, the character "Yu" (于) was interchangeable with "Yu" (於) and "Wu" (烏 - crow/black). In ancient times, the characters "Hu" (呼), "Xu" (吁), "Hu" (乎), and "Yu" (于) shared similar forms and meanings. According to the Shuowen Jiezi: "Yu (于) means Yu (於), depicting the gradual expansion or release of breath." It further describes "Wu" (烏) as: "Wu is a filial bird; it is a pictograph."

[Origin] During the great enfeoffment in the early Western Zhou Dynasty, the second son of King Wu of Zhou (Ji Fa) was granted the former site of the Shang Dynasty State of Yu (located in present-day Yutai Village, Qinyang, Henan). He was known as Yu Shu and established the State of Yu (邘). His descendants adopted the state's name as their surname, originally written as "Yu" (邘). Because the characters "Yu" (邘) and "Yu" (于) were homophones and used interchangeably in ancient times, some descendants later removed the "city" radical (阝) to become the "Yu" (于) clan.
