Rouputuan, also known as Huiquanbao and Juehouchan, and translated as 〈The Carnal Prayer Mat〉 or 〈The Before Midnight Scholar〉, is a Chinese erotic novel of the Qing Dynasty published under a pseudonym but usually attributed to Li Yu. It was written in 1657 and published in 1693. It is divided into four volumes of five chapters apiece. It was published in Japan in 1705 as Nikufuton with an preface proclaiming it the greatest erotic novel of all time. In the Chinese literary world, the novel was controversial, and has long been banned and censored, but recent opinion holds that it is an allegory which uses its unabashed pornographic nature to attack Confucian puritanism. The prologue comments that sex is healthy when taken as if it were a drug, but not as if it were ordinary food.
A zafu (Japanese: 座蒲) or putuan (Chinese: 蒲团) is a round cushion. Although also a utilitarian accessory, it is most well known for its use in zazen Zen meditation.
