Who can tell me what font this is? Thank you!

That kind is from the Song Dynasty!

Song style is a kind of printing style, which originated in the Song Dynasty and was established in the Ming Dynasty. It is the most widely used font in modern printing industry. In the Song Dynasty, "culture and education were promoted while military affairs were suppressed", and culture showed unprecedented prosperity. In Song Dynasty, the printing and publishing industry entered the golden age, with developed block printing and numerous book engraving centers, which developed rapidly. During the Yuan and Ming Dynasties, a large number of periodicals in the Song Dynasty were reprinted, so Song-style characters with beautiful and dignified fonts and easy writing and engraving gradually became popular fonts in the printing and publishing industry at that time.

According to the different glyphs, Songti characters can be divided into calligraphy characters and treasure characters. The font is square, the strokes are horizontal and vertical, the thickness is clear, the edges and corners are sharp, rigorous, neat and even, and the strokes are regular, which makes people feel comfortable and eye-catching when reading.

Song style also includes other imitation Song styles.

Imitation of Song Dynasty is a printing font, which imitates the style of European characters in the Northern Song Dynasty, and its lines are slightly longer. With the economic development in Song Dynasty, the engraving printing industry developed rapidly. In order to meet the needs of the printing industry, sculptors require a more neat and standardized font than regular script. After continuous exploration, they created a more standardized block printing font. This font is very close to regular script, and there is little difference between horizontal and vertical strokes. In the Ming Dynasty, this kind of seal cutting font developed more standardized and became a slightly angular font. In the Qing Dynasty, there was a printed version of Wuying Hall, which used imitation Song fonts. At the beginning of the 20th century, Ding Fuzhi and Ding of Qiantang collected the engraving fonts of the Song Dynasty, and copied a printed movable type font with equal thickness in two directions, beautiful strokes, rectangular shape, exquisite and beautiful appearance. Now, this font has become a very widely used font in our daily life.

And Juzhen's imitation of Song Dynasty.

A book printed in imitation of movable type in Song Dynasty is called Juzhen Imitation Song Edition. Juzhen edition is another name for movable type edition. During the Northern Song Dynasty and the Qing Dynasty, Bi Sheng, a Buyi nationality, invented clay movable type. Pilers in the Ming Dynasty used lead to make movable type for printing books. During the reign of Kangxi in the Qing Dynasty, ancient and modern books were compiled and printed with copper cast movable type, and their words were stored in Wuying Hall. During the Qianlong period, many of them were stolen because of their age. At that time, copper used for coinage was scarce, so these copper movable types were destroyed and used for coinage. During the Qianlong period, the Open Library compiled Sikuquanshu. Emperor Qianlong ordered the treasury officer to select rare books from Yongle Dadian and books submitted by various provinces for revision and publication, and Jin Jian, assistant minister of the Ministry of Housing, presided over the matter. Golden bamboo slips are made of jujube wood into more than 250 thousand kinds of movable type, which are used to print selected rare books. Emperor Qianlong thought that the name movable type edition was not elegant enough, so he named it Juzhen edition.
