同音選字法

同音選字法係基於反切原理，反切不同拼音，拼音用英文或外文拼出來，原理也是一樣。
PINYIN 拼音 is like spelling the sound based on the set of alphabets. Chinese does not do it this way. They use something called 反切.
I called my system 同音選字法 because you will look for the word in Chinese to find the proper chinese with the disired sound, then look up the tones and pick the desired character.

You need only two clicks to find the character you want.
I also add other easy ways to find characters or symbol in sets such as time, money, quantity, numbers and even English and Greek characters. Here you go. Express yourself in cantonese chinese! You can learn chinese with it.
