Ma Huan
In Yingya Shenglan, Ma Huan describes the writing system used in Majapahit. For the writing, they had known the alphabet using "So-li" (Chola - Coromandel/Southern India) letters. There is no paper or pen, they use "Chiao-chang" ("kajang") or palm leaf ("lontar"), written by scraping it with a sharp knife. They also have a developed language system and grammar. The way the people talk in this country is very beautiful and soft.
