Moirang Sai (Old Manipuri: Moilang Sai) or Moirang Shai (Old Manipuri: Moilang Shai) is a traditional Meitei musical performing art form, that narrates the story of Khamba and Thoibi.

[a][1][2][3] During the time period between the 1950s and the 1980s, Moirang Sai was performed popularly for entertainment in social gatherings and weddings.

[1][3] In the 2010s, Ima Thoinu got only a few students to learn the endangered art form, which was the only means to keep it alive.

Mangka is re-popularising the nearly extinct art form among the present youth once again.

[4] On 4 October 2020, the Nongpok Ingouba Cultural Academy (NICA), Yairipok Top Chingtha Oinamthong Leirak, under the aegis of the Ministry of Culture, Government of India, organised a workshop cum production program, on "Moirang Sai" at the Yairipok Top Lai Community Hall, to protect and popularize the traditional art of 'Moirang Sai'.
