In the late Ming Dynasty, Hu Zhengyan contributed greatly to the improvement of engraving printing technology. The new printing technology of "? Edition" and "arch flower" adopted by him has raised the printing technology of ancient China to a new level.

The so-called "? Version" printing is to engrave and divide each color into a version according to the color situation of the color drawing manuscript, and then follow the principle of "light to dark, light to dark" , Color-by-color overprint, and finally complete a color print similar to the original. Because this color separation printing plate is similar to "??", the Ming Dynasty called this printing method "? Plate" printing, also known as color engraving printing. After the mid-Qing Dynasty, it was called woodblock watermarking.
It is Hu Zhengyan in the late Ming Dynasty who made a tremendous contribution to the experiment and popularization of "? Edition" printing.
Hu Zhengyan, from the word Hui, originally from Huizhou, lives on the side of the Jilong Mountain in Nanjing. Because there are more than ten bamboos planted in the courtyard of his home, he named his room "Shizhuzhai". He was a bold and innovative art creator during the late Ming Dynasty. Good at seal carving, painting, ink making and many other crafts. He presided over the engraving of "Shizhuzhai Calligraphy and Painting" and "Shizhuzhai Notes", becoming an epoch-making work in the history of printing. The "Arch Flower" printing he pioneered also occupies an important position in the history of printing. Until today, embossing printing has been widely used in various decoration printing.

The content of "Ten Zhuzhai Calligraphy and Painting" is divided into eight types: calligraphy and painting, bamboo, plum, orchid, stone, fruit, quill and Mohua. There are also celebrity inscriptions on many boards, and it is a textbook for painting.
Another book presided over by Hu Zhengyan is "Shi Zhuzhai's Notes". The engraved version of "Ji Zhuzhai's Calligraphy" is about to be completed soon. (AD 1644) All marking work was completed. "Note Book" is more exquisite and beautiful than "Calligraphy and Painting Book", and has been highly praised. It is worth mentioning that Hu Zhengyan used the "Arch Flower" printing technology that he pioneered in the printing of "Paper Notation", which is also an immortal work in the history of printing.

A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia (see squat toilet). In urban areas, flush toilets are usually connected to a sewer system that leads to septic tanks in isolated areas. The waste is known as blackwater and the combined effluent including other sources is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet.
