The Three Zhangs, or Three Changs (三張) is a term that refers to the three generations of faith-healers in the Zhang family:
- Zhang (Dao)ling (張陵/張道陵)
- Zhang Heng (张横)
- Zhang Lu (張魯)
The term is also frequently used to refer to the three Zhang brothers Zhang Jue, Zhang Bao and Zhang Liang of the Yellow Turbans, but 'officially' it only refers to the first mentioned three Zhangs.
