The present invention provides a Chinese character input method and system, which is suitable for a small data processor, such as the mobile phone with standard keyboard proposed by the CCITT (consultative committee in international telegraphy and telephony), for the user inputting Chinese messages into the mobile phone using multiple sets of virtual keyboards and the displayed phonetic notation or the Roman spelling symbols. The Chinese character input method and system are characterized that using a plurality of virtual keyboards to display the Chinese phonetic notations or the Roman spelling symbols. Each virtual keyboard has a plurality of virtual buttons, which are corresponded to the physical keyboard on the CCITT standard keyboard of the mobile phone with an one-to-one corresponding relationship. The Chinese character input method and system can let the user only use the 12 symbol buttons on the CCITT standard keyboard to input the Chinese messages. Because each virtual keyboard needs only to be configured with 12 virtual buttons, the size of each virtual button is larger than the conventional one so as to let the user more easily to see and select the required virtual buttons.
