-    <p>
-      The Pinyin input method is designed for entering Chinese text by
-      using Pinyin or Zhuyin.
-    </p>
-    <p>
-      Input methods are typing systems allowing users to input complex languages.
-      They are necessary because these contain too many characters to simply be laid
-      out on a traditional keyboard.
