Jiajing Emperor in the context of "Daoshi"

Wucai (五彩, "Five colours", "Wuts'ai" in Wade-Giles) is a style of decorating white Chinese porcelain in a limited range of colours. It normally uses underglaze cobalt blue for the design outline and some parts of the images, and overglaze enamels in red, green, and yellow for the rest of the designs. Parts of the design, and some outlines of the rest, are painted in underglaze blue, and the piece is then glazed and fired. The rest of the design is then added in the overglaze enamels of different colours and the piece fired again at a lower temperature of about 850°C to 900°C.

It has its origins in the doucai technique. The usual distinction made with doucai, which also combines underglaze blue with overglaze enamels in other colours, is that in wucai only parts of the design include blue, and these cover wider areas, and are often rather freely painted. In doucai the whole design is outlined in the blue, even if parts are overlaid by the enamels and invisible in the finished product. Some parts may also be painted in the blue. However, this is not true of all pieces classified as doucai, especially from the 18th century onwards. Fragments of incomplete examples, only done in blue, have been excavated from waste tips at the kiln.

Water Margin (simplified Chinese: 水浒传; traditional Chinese: 水滸傳; pinyin: Shuǐhǔ Zhuàn), also called Outlaws of the Marsh or All Men Are Brothers, is a Chinese novel from the Ming dynasty that is one of the preeminent Classic Chinese Novels. Attributed to Shi Nai'an, Water Margin was one of the earliest Chinese novels written in vernacular Mandarin Chinese.

Set during the Northern Song dynasty (around 1120), the story follows a group of 108 outlaws who gathers at Mount Liang (also known as Liangshan Marsh) to rebel against the government. Later they are granted amnesty and enlisted by the government to resist the nomadic conquest of the Liao dynasty and other rebels. While the book's authorship is traditionally attributed to Shi Nai'an (1296–1372), the first external reference to the novel only appeared in 1524 during the Jiajing reign of the Ming dynasty, sparking a long-lasting academic debate on when it was actually written and which historical events the author had witnessed that inspired him to write the book.

The Longqing Emperor (4 March 1537 – 5 July 1572), personal name Zhu Zaiji, was the 13th emperor of the Ming dynasty, reigning from 1567 to 1572. He was initially known as the Prince of Yu (裕王) from 1539 to 1567 before he became the emperor. He succeeded his father, the Jiajing Emperor.

After the death of the Jiajing Emperor, the Longqing Emperor inherited a country in turmoil due to years of mismanagement and corruption. Recognizing the extent of the chaos caused during his father's lengthy reign, the Emperor worked to restore order in the state administration. He reinstated talented officials who had been previously exiled and dismissed corrupt officials and Taoist priests who had surrounded the Jiajing Emperor. Additionally, he lifted the ban on foreign trade, boosting the empire's economy, and reorganized the border troops to strengthen security on the inland and coastal borders. The seaports of Zhejiang and Fujian were fortified to defend against coastal pirates, who had been a constant nuisance during the previous government. The Emperor also successfully repelled Altan Khan's Mongol army, which had breached the Great Wall and reached Beijing. A peace treaty was signed shortly after, allowing for the resumption of the exchange of horses for silk.

The 1556 Shaanxi earthquake (Postal romanization: Shensi), known in Chinese colloquially by its regnal year as the Jiajing Great Earthquake "嘉靖大地震" (Jiājìng Dàdìzhèn) or officially by its epicenter as the Hua County Earthquake "华县地震" (Huàxiàn Dìzhèn), occurred in the early morning of 2 February 1556 in Huaxian, Shaanxi, during the Ming dynasty.

Most of the residents there lived in yaodongs—artificial caves in loess cliffs—which collapsed and buried alive those sleeping inside. Modern estimates by China Earthquake Administration's publications put the direct deaths from the earthquake at roughly 100,000, while over 700,000 either migrated away or died from famine and plagues, which summed up to a total reduction of 830,000 people in Imperial hukou registration. It is one of the deadliest earthquakes and one of the deadliest natural disasters in Chinese history.
