Li was born to an upper-class family in Sankakuyū (),
Japanese Taiwan (modern-day
Sanxia District,
New Taipei City) on 13 March 1902. He began to demonstrate a propensity for painting in his early years. In 1918, he was accepted into the Painting Division of the Taiwan Governor-General's National Language School. He taught himself painting after school through a copy of A Collection of Lectures, which he ordered from Japan through post. Upon graduating, he taught at Zuihō Public School (in modern-day
Ruifang District). During this time, he participated in the Summer Art Seminar organized by
Kinichiro Ishikawa. His works 'Still Life and Backstreets of Sanxia' were selected for the first and second Taiwan Art Exhibitions (Taiten), respectively. He then obtained his family's consent to go to
Japan to further his painting studies. In 1929, he was accepted by the Division of Western Painting at the Tokyo School of Fine Arts, where he studied with teachers such as Okada Saburousuke and Kobayashi Mango. == Work and public life ==
