你好, こんにちは, 안녕하세요

Chinese (Simplified)


Chinese (Tranditional)





나라말이 중국과 달라, 한문・한자와 서로 통하지 아니하므로, 어리석은 백성들이 말하고자 하는 바가 있어도, 끝내 제 뜻을 펴지 못하는 사람이 많다. 내가 이를 불쌍히 여겨, 새로 스물 여덟 글자를 만드니, 사람마다 하여금 쉽게 익혀, 날마다 씀에 편하게 하고자 할 따름이다.

Use the lang attribute to the container element to have better Asian CJK (Chinese, Japanese and Korean) font support.

<p lang="zh-Hans">革命不是请客吃饭,不是做文章……</p>
<p lang="ja">祇園精舎の鐘の声、諸行無常の響きあり……</p>
<p lang="ko">나라말이 중국과 달라, 한문・한자와 서로 통하지 아니하므로……</p>

And you can use the cjk class or the lang attribute to add spacing between underlines and strike-through text for better Chinese and Japanese readability.



<p class="cjk"><u>祇園</u><u>精舎</u>の鐘の声、諸行無常の響きあり。……</p>
<p class="cjk"><del>祇園</del><del>精舎</del>の鐘の声、諸行無常の響きあり。……</p>
