Mu Zeng ({{zh|木增}}, September 19, 1587 – September 9, 1646), also known as A-chai A-ssu in Nakhi, was the native chieftain of Lijiang between 1597 and 1623. He was born to Mu Qing ({{zh|木青}}) and Ashijia ({{zh|阿室加}}) and ascended the throne when he was ten years old. The chieftain was known for his literature and wrote many anthologies.《木氏宦谱》(木氏宗谱)，【清】木钟等编《中国西南古纳西王国》(The Ancient Nakhi Kingdom of Southwest China)，Joseph Rock 著，刘宗岳译，云南美术出版社，1999年4月出版，{{ISBN|978-780-586-514-0}}
