Can Koreans read traditional Chinese characters?

Let's just say that people in their forties or older (educated) can understand part of it. South Korea is actually a country with Chinese characters, and ancient Korean characters are the official characters. Therefore, it is a big joke that South Korea now claims to be the country that invented Chinese characters. South Korea banned the use of Chinese characters from the late 1950s. Previously, South Korea used Korean and its corresponding Chinese characters. People under the age of 40 in South Korea are called "the generation who don't understand Chinese characters" because they have never received Chinese character education since childhood.
