Besides the 30,000 frequently used phrases, there are 12 professional word-stocks are appended. The new function to construct phrases from taking the Characters from the screen and delete the phrases from the word-stock is convenient and agile. Also the Wangma Intellectual Pinyin Input Method is designed to the software. The unique Help and encoding prompt functions are added to the new software. The originated 'Retractile Antenna' Character sets switch method reduces identical codes greatly so as to improve the inputting speed greatly. The software adopts new simplified and traditional Character Roots list and originally creates the Three Grades to learn the Cross-codes that enables the beginners to learn the Method easily.
