Please answer the following question: Information: - Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term "masonry" can also refer to the units themselves. The common materials of masonry construction are brick, building stone such as marble, granite, travertine, and limestone, cast stone, concrete block, glass block, and cob. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can significantly affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. - Emperor Wen of Sui (; 21 July 541 13 August 604), personal name Yang Jian (), Xianbei name Puliuru Jian (), nickname Naluoyan (), was the founder and first emperor of China's Sui Dynasty (581618 AD). He was a hard-working administrator and a micromanager. The Sui Shu records him as having withdrawn his favour from the Confucians, giving it to "the group advocating Xing-Ming and authoritarian government."

Traditionally, the term brick referred to a unit composed of clay, but it is now used to denote any rectangular units laid in mortar. A brick can be composed of clay-bearing soil, sand, and lime, or concrete materials. Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. Two basic categories of bricks are "fired" and "non-fired" bricks. - The Communist Party of China (CPC) is the founding and ruling political party of the People's Republic of China (PRC). The CPC is the sole governing party of China, although it coexists alongside eight other legal parties that comprise the United Front; these parties, however, hold no real power or independence from the CPC. It was founded in 1921, chiefly by Chen Duxiu and Li Dazhao. The party grew quickly, and by 1949 the CPC had driven the nationalist Kuomintang (KMT) government from mainland China after the Chinese Civil War, thus leading to the establishment of the People's Republic of China. The CPC is currently the world's second largest political party with a membership of 88.76 million as of 2016 (while the Indian Bharatiya Janata Party appears to have remained the largest with a membership of 110 million as of the previous year, 2015).

The manufacture of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, insulation, plumbing, and roofing work. They provide the make-up of s and structures including homes. - China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia.
