A Brief History of China Fine Arts compiled by the Department of Fine Arts History of the Central Academy of Fine Arts, published by China Youth Publishing House; A Brief History of Foreign Fine Arts, Higher Education Press. I really don't have time. You can read "A Guide to the History of Art Postgraduate Entrance Examination", Guangxi Fine Arts Publishing House. This book condenses the essence of art history and theory, and is worth referring to.

Others can read The History of Landscape Painting in China, written by Chen Chuanxi and published by Tianjin People's Fine Arts Publishing House.

As for techniques, I usually accumulate them.

Wish you success!
