More than 87% of Chinese parents have signed their children up for online tutoring sessions to supplement their education, according to a recent survey from China Youth Daily.

English and math have proven the most popular online courses, respectively attracting 68.7% and 58.5% of surveyed parents, said China Youth Daily on Thursday.

Entertaining classes that encourage kids to pursue personal hobbies were ranked third most popular, with the Chinese language coming in fourth.

A total of 1,523 parents took part in the survey. They mainly attributed the booming online tutoring market in China to the fact that the courses are immune to anti-COVID-19 measures.

Online courses also spare parents the stress of taking their children to extracurricular training centers and bringing them back home after their classes, according to respondents.

Most respondents (83.5%) expressed positivity toward the quality of online tutoring, while just 0.5% expressed complete disapproval.

Their biggest concern was the impact of online classes on their children's eye health, with 49.3% of respondents citing this issue.

More than 95% of respondents called on authorities to enhance scrutiny over online training platforms in terms of advertisement content, operation licensing and financial safety.
