Sangwan's mother had taught the girl to read. With this elementary skill, she enrolled at the all-girls school of Wat Anongkharam, a nearby temple whose abbot recognised the need for girls to have an education. She then studied at Suksanari, but left after only a month due to lack of funds. She nonetheless maintained her reading habit by regularly visiting her aunt’s friend, who ran a library of books for rent. She read the Thai classics, such as "Inao", "Phra Aphai Mani", and "Sangsilchai".
