Generally speaking, it was possible for people without a foundation to read traditional Chinese books, but they had to make sure that the version of the book they read was correct, legal, and that there were no translation errors or wrong simplifications of traditional Chinese. Reading traditional Chinese books required some basic Chinese knowledge such as traditional Chinese characters and strokes, basic grammar, and reading comprehension. If you have a certain understanding of traditional Chinese, it will be easier to read traditional Chinese books because you may encounter some confusion between simplified Chinese and simplified Chinese grammar when reading simplified Chinese books. Reading traditional Chinese books also required a certain amount of patience and perseverance because traditional Chinese characters and strokes were more complicated and required a certain amount of time and energy to adapt and understand. If you have doubts about reading traditional Chinese books, it is recommended to first read some traditional Chinese classic literary works such as "Dream of the Red Chamber" to establish a certain foundation of traditional Chinese before trying to read other traditional Chinese books.
