Outside Tiewei Mountain

"Beyond Tiewei Mountain" contains the strange things recorded in the past years. The Buddhist scriptures say that beyond Sumeru, there is an iron-encircled mountain, surrounding it, which is the boundary of the world. People within the boundary think that the boundary is everything; things outside the boundary occasionally cross the boundary and are called strange, monsters, auspicious, and heavenly books - the names are different, but in fact they are the same: they do not belong here, but they are here. I have been recording strange things here for fifteen years. I recorded one but forgot one. The records of the teacher's sect are known as "Hui Xi Lu" in the world, and they are passed down like incense from generation to generation. The remaining volume is privately titled "Beyond Tiewei Mountain". Therefore, what is recorded in this book is full of incomplete information and self-contradictory. Unless I am careless, I really can't remember everything. Someone with good intentions asked: If I forget, how can I record it? Yu said: It is precisely because I will forget that I have to record it. If one day I even forget this book, I hope that those who read this book will remember it for me.
