[The preface] says that Xueqin worked on this book and revised it many times. In that case, who wrote all this preliminary section up to here? Evidently this is just the author playing a trick on us. He resorts to this sort of device in many other places besides this one. It's what painters call the "mist and cloud" technique. The reader, if he is wise, will be very careful not to be taken in by it.
