As a scholar, she has been studying and acquiring new knowledge throughout her life. Her Royal Highness is articulate in several languages, including English, French, Chinese, Pali, Sanskrit, and Cambodian. Whenever and wherever she travels, she always carries a notebook and pen to record all the information she gathers.

Hands-On Experience

The Princess began learning at a tender age by watching her royal parents at work while following them everywhere they went to check on their projects. This gave her hands-on experience in learning about Thai people from all walks of life. Her perseverance and efforts to improve the people’s quality of life have been recognized internationally.

Cultural Patronage

Her Royal Highness also excels in musical, literary, and visual arts. On February 26, 1985, the government announced the royal birthday, April 2, as “National Heritage Preservation Day” in recognition of Her Royal Highness’s long-standing interest in Thai arts and culture and her support for the preservation of Thai heritage. Later, in 1988, Her Royal Highness was presented with the title of “Supreme Patroness of Thai Cultural Heritage.”
