“It is over twenty years since I first heard of Hong-lou meng and the great fascination it holds for its readers (despite the fact that there has never been a complete or definitive text). I was once lucky enough to borrow a copy from a friend. Reading it (in this incomplete state) was indeed a tantalizing experience.
In the spring of this year, my friend Cheng Weiyuan came to see me and showed me the complete text that he had purchased. 'This,' he said, 'is the fruit of my labours over several years. Bit by bit I have pieced it together, with a view to publishing it for fellow-lovers of the novel. As you are at a bit of a loose end, and in need of a restorative, will you share the labour [of preparing the manuscript for the press] with me?'
Although it was only a novel, the book contained nothing contrary to the tenets of Confucian teaching, and so I gladly accepted, and fell upon the task with the eagerness of the Persian slave when he saw his pearl! Now that the work is done, I have described these circumstances for the reader's information.”
