The Diez de Octubre School (Chinese: 中華三民聯校; pinyin: zhōnghuá sānmín lián xiào; lit.

'Chung Wa-San Min United Colleges'; CDO), is a Peruvian private school headquartered in Lima—in the districts of Breña and San Miguel— and Chiclayo.

It was founded in 1924 by a group of women from the Catholic Ladies' Association of the Chinese Colony.

The college offers early, primary and secondary education studies.

[4] The student population was always increasing and as a result of this, the promoters created the "Confucio" annex in the San Miguel district in 1982, and the "Sun Yat Sen" school in the city of Chiclayo in 2006.
