As far as European regular script is concerned, I personally prefer Teacher Lu Zhongnan and the Tian brothers. I just bought this book.
Teacher Lu Zhongnan is very accomplished in regular script, especially European-style small regular script. His brushwork removes the metal and stone energy of the inscriptions, giving people a feeling of sudden enlightenment. If the questioner needs to practice regular script, the author recommends comparing the rubbings with this book, and many incomprehensible points can be clarified. After all, the best way to learn the Dharma is to not just study this book.
