The autographed manuscripts that are of the "utmost rarity" reveal Mao's deep continuing interest in classical Chinese literature, Sotheby's auction house said in a statement.
The notes those were valued between 60,000 and 80,000 pounds were written a year before Mao died in 1976.
As Mao's health deteriorated, his sight was failing and he struggled to read. Therefore, Di Lu, a literary expert and a scholar was appointed to read to him.
Because Mao was having trouble articulating words, Lu asked him to write his thoughts down on a notepad to ease communication, 'BBC News' reported.
The manuscripts written by Mao were "exceptionally rare on the market, which makes it very difficult for us to estimate them in the first place," Gabriel Heaton, a books and manuscripts specialist from the auction house said.
The notes were bought by a Chinese collector, after attracting interest from around the world, the auction house said.
