Zhu gave away a total of 23.98 million yuan (USD 3.9 million) earned from royalties on some of his books -- to help poor students and teachers and renovate school facilities, according to wealth publisher Hurun's Philanthropy List 2014.
He ranked 60th on the list, released yesterday, after technology billionaires, property tycoons and investment gurus.
Zhu was China's premier from 1998 to 2003. He was known for his tough style with other officials but credited with pushing deep economic reforms.
Many Chinese leaders have published books after retirement and donations of royalties are often reported by state media, though usually of much smaller value.
The books that contributed to Zhu's donation were collections of transcripts of his speeches and comments since the late 1980s, when he was mayor of Shanghai.
Jack Ma, China's richest man and founder of e-commerce giant Alibaba, was ranked as the most generous person in the country, after he donated a 1.4 per cent stake in the firm -- worth USD 3.5 billion according to yesterday's share price -- to set up an environment, healthcare and education charity, said a statement accompanying the list.
