Old Lisu, also known as biblical script, Fu Neng Ren script, is a script that imitates the Latin alphabet and is specifically used to record Lisu. The appearance of this text is similar to the capital Latin letters, and is marked with a tone to show the tone. The text is all sans serif text, only capitalized, and there are many differences in phonetic transcription from the existing Latin alphabet, so it is not compatible. Li-Su Keyboard Plus can quickly type, the keyboard has vibration. You can slide down to directly type in the previewed characters to speed up typing.
