After the Japanese colonial era, the policy of annihilating Korean culture from the 1920s began in the 1920s. In 2010, Mr. Joo founded the Joseon language Organization and took the lead in the study and dissemination of Hangeul(Korean language) even in the harsh environment of the time. He also conducted lectures and magazine publications. One of the biggest feats of the organization was publishing compiled dictionaries. In the midst of Japanese oppression, the Joseon language organization decided to found and commemorate Hangeul Day in order to remember the spirit of the nation. In 1936, Japan abolished Korean language education to destroy the identity and language of Koreans and arrested 33 members who cooperated in dictionary compilation. Those charged with civil war were imprisoned, and some of them died in prison.
By the effort and sacrifice of the people who strived for preserving Korean language, the first volume of dictionary was published in 1947 and the organization was renamed as Korean language society which keeps carrying out a lot of international Korean language conferences and projects these days.
