There are many well-written required books for the introduction to architectural history. You can go to the library to read the introductory books of architectural history during your break. I recommend you to have a look at "Preliminary Architecture" and "Architectural Space Geometry Theory". I read these two books when I first learned architecture. The book "Preliminary Architecture" has five chapters, including how to understand architecture, the basic composition of architecture, architecture and society, architecture and environment, and the study of architecture specialty. The basic knowledge of Chinese and western classical architecture and modern architecture, the basic expression methods of tool painting, freehand painting, ink painting, watercolor rendering and other architectural paintings are all-inclusive, and this book is very suitable for beginners.
