Do Koreans still use Hanja?

Hanja has a long history in Korea, dating back to the introduction of Chinese characters around the 2nd century BCE. These characters were adapted to suit the Korean language and were used extensively in various fields, including literature, science, and religion. However, the complex nature and the need for mastering thousands of characters made Hanja a difficult writing system for commoners. This led to the creation of Hangul, a phonetic alphabet, by King Sejong the Great in the 15th century. Hangul was designed to be easy to learn and use, which made it popular among the general population.
