Why did Qian Zhongshu insist on publishing the Pipe awl in traditional Chinese characters?

Simplified characters in many ancient books can't be typed, such as Li Sao, Tian Wen, Jiu Zhang and Tian Wen. Most of the characters in the four books are like this. Simplified characters combine many, many traditional characters into one. Then Qian Zhongshu couldn't make it clear, and it was all messed up.
