켜자마자 한자-잠금화면 사자성어, 천자문 + 공부 알람 APP

The "Hanja as Soon as You Turn It On" app is a revolutionary invention that uses the lock screen to naturally and subconsciously incorporate Hanja and culture into your daily life. Easily study one Hanja character every time you use your phone! Your language and life will change without you even realizing it.

Even if you know the importance of Hanja and Hanja culture, you often find it hard to find the time to study them. And you don't have a proper method. For those who find this app incredibly useful, this app is invaluable.

If you briefly study one Hanja character every time you use your phone 100 times a day, whether it's watching YouTube, checking KakaoTalk, or checking the time, you can learn 3,000 characters a month. This automatic study app allows you to study without any special time commitment. It offers tremendous benefits "without much effort."

🟦 You can't speak Korean well without knowing Hanja.
70% of Korean vocabulary consists of Chinese characters. In other words, Chinese characters are Korean. In particular, current affairs, economic terms, technical terms, and academic terms are mostly Chinese characters. Even if you know the vocabulary in Korean, if you don't know the meaning of the Chinese characters, it's difficult to use the language accurately and understand the text. (People with literacy and general knowledge problems often have poor Chinese character skills.) Knowing Chinese characters well will help you speak Korean well. This will make you more knowledgeable and better able to express your thoughts. They say language is a tool for expressing thoughts. The better the tool, the better your thoughts will be. I hope Chinese characters will help you cultivate the "power of thought."

🟥 Mastering Chinese characters and Korean avoids embarrassment!
Especially for those in social life, not knowing Chinese characters can be embarrassing. Do you know the meaning of "supper" in "The Last Supper"? Many people mistake "만" (man) for "full" (fullness), and mistake it for a full or well-prepared meal. However, the word for a lavish meal is often mistakenly used as "성찬" (盛餐), and "만찬" (dinner) here is 晩餐. (※ Breakfast, lunch, and dinner are written with the characters 朝 (morning), 午 (day), and 晩 (late), respectively, to mean breakfast, lunch, and dinner.)

Suppose your company makes a reservation at a nice restaurant for lunch and sends a text message to your boss and business partners saying, "Please join us for dinner today at 1 PM." This will make them see your Korean language skills and general knowledge as lacking, which could erode your value and credibility.

The best accessory is culture.
Chinese characters and the Korean language are the foundation of culture.
