+# pinyin4js
+
+## Introduction
+
+pinyin4js is an open-source JavaScript library that has been adapted to OpenHarmony for converting Chinese characters to Pinyin. It has the following features:
+
+* **Zero dependency**
+
+* **Flexible import and packaging of dictionaries**
+
+  The imported dictionaries can be adjusted as needed. For details, see **src/dict**. All resource scheduling is encapsulated by **PinyinResource**, and the resources can be packaged after being modified.
+
+* **Accurate and comprehensive dictionaries**
+
+  Among the 20903 Chinese characters in the Unicode range of 4E00-9FA5 and 3007, pinyin4js can convert all of the characters except 46 heterogenous characters (which do not have standard pinyin).
+
+* **Fast conversion**
+
+  Test results reveal that pinyin4js takes about 110 milliseconds to convert the supported 20902 Chinese characters.
+
+* **Multiple output formats**
+
+  The output can come with phonetic symbols, without phonetic symbols, phonetic symbols represented by numbers, or Pinyin initials.
+
+* **Common multi-sound character recognition**
+
+  Common multi-sound characters, as in phrases, idioms, and place names, can be recognized.
+
+* **Simplified/Traditional Chinese conversion**
+
+* **Custom dictionaries**
+
+  Custom dictionaries can be added.
