The estimated investment in children's education by China's high-net-worth families totals around 4.6 million yuan ($635,900), with financial planning for children in their early stage of education becoming a trend, according to a report released jointly by Hurun Report and CITIC-Prudential Life on Thursday in Guangzhou, the capital of Guangdong province.

The overall investment in children's education, from kindergarten to the highest education level, includes on-campus and off-campus expenses, according to the report on China's high-net-worth family education.

The main sources of funds for children's education are primarily cash, followed by fixed income, equity and protection funds, according to the report.

Parents of younger children, typically in kindergarten and primary school, place greater emphasis on safeguarding funds, particularly through education savings plans, compared to parents of children in middle and high school.

When planning study abroad funds for their children, the report showed that the financial services that high-net-worth families are most interested in are budget management, international remittances, and insurance services.

Guangdong remains the region with the highest number of high-net-worth families with net assets in the tens of millions of yuan, totaling 300,000 households, followed by Beijing with 299,000 households and Shanghai with 265,000 households, according to the report.
