Open floor-to-ceiling bookshelf ** 1. ** Overall layout ** - In terms of size, if space allowed, a higher bookshelf could be designed, such as a bookshelf that was 2.5 meters high, 1.2 meters wide, and 40 centimeters deep. The interior could be divided into multiple squares of equal width and height. For example, the square was 39 centimeters wide and 37 centimeters high, which was convenient for different types of novels. - In terms of location, it could be placed between the living room and the open kitchen to become a partition and decoration of the space. 2. ** Material and Style ** - The material could be bunny multi-layered solid wood, and the color was like elegant rosewood.

If it was a modern minimalist style, some simple designs could be made on the appearance of the bookshelf, such as using straight lines. 3. ** Function optimization ** - In front of the open bookshelves, a tatami reading corner could be set up. The platform was raised 18CM and was directly made of cement without any keels. The top was covered with wooden floors and red oak steps. Lazy sofas and floor lamps were placed on the platform to create a comfortable reading atmosphere. - In order to solve the problem of dust falling, if the windows in the house were sealed, there would be relatively less dust. It could be cleaned once every 1 - 2 weeks. ** 2. Semi-open (combined with closed) floor-to-ceiling bookshelf ** 1. ** Layout and structure ** - The bookshelf could be designed into a top-down structure. The upper part could be made into a closed cabinet door to prevent dust from entering and could be used to place some infrequently read novels or precious books. The lower part could be designed as an open display cabinet to facilitate the access of recently read novels. - The shelves of the upper and lower cabinets could be made into drawers instead of the traditional ones. This way, it would be more convenient to take books, especially for some small novels. - Or they could design the bookshelves into a combination of open bookshelves and closed bookshelves. For example, they could be arranged in a staggered manner according to a certain proportion to prevent dust from falling and not make the bookshelves look rigid. 2. ** Appearance and Function ** - In terms of appearance, he could use the method of protruding the side panel and retreating the open grid area to create an effect similar to the "simplified version" of the bone grid line bookshelf and improve the texture of the bookshelf. - In terms of functions, the semi-open area could be adjusted to be easy to access or easy to store according to their own needs.

A specially-shaped floor-to-ceiling bookshelf ** 1. ** Corner bookshelf ** - For rooms with corner spaces such as staircases, the design of 365-degree floor-to-ceiling corner bookshelves could be used to make full use of the wall. The straight bookshelves could be combined with the curved staircase or room structure, just like the stairs surging like waves. The bookshelves were set up in the enclosed space of the stairwell. This kind of rhythmic structure was both beautiful and could increase the capacity of the bookshelves. It was very spectacular. 2. ** Curved or Shaped Bookshelves ** - The bookshelf itself could be made into a curved shape or other shapes instead of a straight side.

Introduction to the Great Ming Dynasty

The Ming Dynasty existed from 1368 to 1644. It had 16 emperors and ruled for 276 years. The Ming Dynasty was founded by Zhu Yuanzhang. He was born in the grassroots and rose up in the chaotic times at the end of the Yuan Dynasty. He defeated many opponents and overthrew the rule of the Yuan Dynasty. After Zhu Yuanzhang established the Ming Dynasty, he created the Hongwu rule, but the Guo Huan case, the Kongyin case, the Hu Weiyong case, and the Lan Yu case also buried hidden dangers for the development of the Ming Dynasty. After Emperor Jianwen ascended the throne, the removal of the vassal state triggered Zhu Di, the King of Yan, to launch the Battle of Jingnan. After Zhu Di ascended the throne, he created the "Yongle Prosperity" and took many measures in military, political, cultural, diplomatic and other aspects, such as personally conquering Mobei, setting up the Cabinet East Factory, moving the capital to Beijing, editing the Yongle Grand Ceremony, sending Zheng He to the West, etc. After that, the father and son of Emperor Renzong and Emperor Xuanzong of the Ming Dynasty recuperated and built up strength. History called it the "Rule of Renxuan". During the period of Emperor Yingzong of the Ming Dynasty, there was a "Tumu Castle Rebellion". 500,000 elites were buried and Emperor Yingzong was captured. Emperor Jingtai was ordered to stabilize the political situation in the face of danger. Later, Emperor Yingzong was restored. Emperor Xianzong of Ming Dynasty redressed the unjust case, but did not go to court in the later period. Emperor Xiaozong of the Ming Dynasty created "Hongzhi Zhongxing". Emperor Wuzong of the Ming Dynasty favored the Eight Tigers and acted unruly. Emperor Jiajing faced the "Great Ceremony Discussion Event". In the early stage, he rectified the court program. In the later stage, he believed in Taoism and favored Yan Song. He did not go to court. In the early days of the Ming Dynasty, the country was strong and prosperous, with the rule of Hongwu, the prosperity of Yongle, the rule of Renxuan, and other prosperous scenes. In the later period, although the emperor and ministers tried their best to maintain it, the Ming Dynasty gradually declined due to various factors such as the fatuous emperor, the corruption of the ruling class, internal and external troubles, etc. In the Ming Dynasty, the prime minister system was abolished and the cabinet system was established. At first, the emperor needed to be diligent to ensure the operation of the system. Later, the emperor was lazy and eunuchs monopolized power. In the military, there was a system of guards and military households, which could not meet the needs of national defense and war in the era of Qi Jiguang. In terms of official salary, the extremely low salary made it a hidden rule for officials to accept gifts.
