Which dynasty improved papermaking?

The improvement of papermaking was in the Han Dynasty and the Eastern Han Dynasty. Papermaking is one of the four great inventions in China, which was invented in Han Dynasty and Western Han Dynasty. China is the first country in the world to raise silkworms and weave silk. In ancient China, the working people spun silk from superior cocoons, and the remaining evil cocoons and diseased cocoons were made into silk floss by bleaching. After floating, some residual flocs will be left on the mat. When the flossing frequency is high, the residual flossing on the pad will accumulate into fiber sheets, which can be peeled off after drying and can be used for writing. This kind of floc is called "He Qi" or "square floc" in ancient books because of its small number of by-products.

The Eastern Han Dynasty (25-220) is another unified Central Plains dynasty in China history after the Western Han Dynasty. It spread to the 18th Emperor in 1995, and was called the Han Dynasty together with the Western Han Dynasty.

At the end of the New Dynasty, the Red Eyebrow Uprising in Greenwood broke out, and Liu Xiu, the imperial clan of the Western Han Dynasty, took advantage of the situation. In 25 AD, Liu Xiu proclaimed himself emperor in Juancheng, and later made Luoyang his capital, continuing the title of "Han", which was called the Eastern Han Dynasty in history. During the Eastern Han Dynasty, the power of Sangong was greatly weakened, and the power of Shangshutai was promoted. During the reign of Emperor Hanming and Zhang Han, the Eastern Han Dynasty entered its heyday, which is known as the reign of Zhang Ming. In the later period of Zhang Han, consorts became more and more overbearing. After Han and Emperor ascended the throne, the consorts were eliminated, and the national strength of the Eastern Han Dynasty reached its peak, which was known as Yuan Long through the ages.
