Chinese vowel derivation system

The present invention provides a Chinese binary syllabification system. Simple finals are configured to derive compound finals, and all the vowels are expressed by one symbol to form a whole Chinese binary syllabification character system. When the simple finals a, e and o add prefix to form the compound finals, punctuating at the outer side of the circle expresses adding i at the front, punctuating in the circle expresses adding u at the front, and punctuating at the outer side of the circle and in the circle expresses adding v at the front, namely 'prefix punctuating'. A dome or a flat top A is configured to form a half-opened symbol which is taken as an a rhythm element, wherein '-' type extending at the left direction expresses adding suffix n (front nasal), and the '-' type extending at the right direction expresses adding suffix n (back nasal), namely 'suffix adds '-''. The '-' in the middle of the E is changed to '|' (the a rhythm element turns left 90 degrees) to form an e rhythm element, the '|' exte
