Int I, start;
Char c;

If (string. IsNullOrEmpty (value) return null;

Start = 0;
List = new List <string> ();

For (I = 0; I <value. Length; ++ I)
{
C = value [I];
If (ChineseChar. IsValidChar (c ))
{
If (I> start)
{
List. Add (value. Substring (start, I-start ));
}
ChinChar = new ChineseChar (c );
List. Add (chinChar. Pinyins. First (). Substring (0, chinChar. Pinyins. First (). Length-1). ToLower ());
Start = I + 1;
}
}

If (I> start)
{
List. Add (value. Substring (start, I-start ));
}
Return list;
}
}

Result:
