Shuowen Jiezi states: This is an ancient form of the character yang.

Records of the Grand Historian (Shiji), section Annals of the Xia (Xia benji) writes it as: From Mount Bozhong flows the Yang.
For further details, see the eleven-stroke entries.
Also, Guangyun pronounces it as yang (rising tone). Jiyun, Yunhui, and Zhengyun pronounce it as yi (rising tone). It is pronounced the same as yang (rising tone).
Wangyang describes the appearance of water. Another interpretation of yangyang is that it refers to something without boundaries. Also, hangyang is used to describe a vast and expansive appearance. Zuo Si, in his Rhapsody on the Capital of Wu (Wu du fu), uses the description hongrong hangyang.
Jiyun notes that this character is sometimes written in a variant form (tàng).
