The following biography was machine translated from his Korean Wikipedia article, with a little copyediting.

Originally from Jeonju, Jeonbuk, he began studying Go at the age of four and was coached by Ha Sung Bong. In 2017, he joined the 7th Regional Recruitment Competition. In 2018, he reached the round of 16 of the 6th Hachansuk National Boating Gifted Baduk Tournament.

This seems to be the article of the "Hachansuk National Boating Gifted Baduk Tournament" (하찬석 국수배 영재바둑대회).
