But the Khmer were the first people who invented firework, according to Chau tha Guan , the Chinese embassador( spy ) who came to Cambodia in 1294-1297 . He brought the invention of firework and fire crackers back to China. Also, the model of Angkor wat (one of Chau tha Guan favorite temple ) was sketched in Chinese fashion to make the forbidden kingdom in Beijing.
thats a cute story.
China had rockets by 1200s.

The design of the Forbidden City, from its overall layout to the smallest detail, was meticulously planned to reflect philosophical and religious principles, and above all to symbolise the majesty of Imperial power. Some noted examples of symbolic designs include:
* Yellow is the color of the Emperor. Thus almost all roofs in the Forbidden City bear yellow glazed tiles. There are only two exceptions. The library at the Pavilion of Literary Profundity (文渊阁) had black tiles because black was associated with water, and thus fire-prevention. Similarly, the Crown Prince's residences have green tiles because green was associated with wood, and thus growth.[38]
* The main halls of the Outer and Inner courts are all arranged in groups of three — the shape of the Qian triagram, representing Heaven. The residences of the Inner Court on the other hand are arranged in groups of six — the shape of the Kun triagram, representing the Earth.[11]
* The sloping ridges of building roofs are decorated with a line of statuettes lead by a man riding a phoenix and followed by an imperial dragon. The number of statuettes represents the status of the building — a minor building might have 3 or 5. The Hall of Supreme Harmony has 10, the only building in the country to be permitted this in Imperial times. As a result, its 10th statuette, called a "Hangshi", or "ranked tenth" (Chinese: 行什; pinyin: Hángshí),[50] is also unique in the Forbidden City.[62]
* The layout of buildings follows ancient customs laid down in the Classic of Rites. Thus, ancestral temples are in front of the palace. Storage areas are placed in the front part of the palace complex, and residences in the back.[63]

Architecture
The Forbidden City, the culmination of the two-thousand-year development of classical Chinese and East Asian architecture, has been influential in the subsequent development of Chinese architecture, as well as providing inspiration for many modern constructions. Some specific examples include:
* Emperor Gia Long of Vietnam built a palace and fortress that was intended to be a smaller copy of the Chinese Forbidden City in the 1800s. Its ruins are in Huế. In English it is called the "Imperial City". The name of the inner palace complex in Vietnamese is translated literally as "Purple Forbidden City", which is the same as the Chinese name for the Forbidden City in Beijing.
* The 5th Avenue Theatre in Seattle, Washington was designed to incorporate elements of classical Chinese architecture and interior decoration. The ceiling of the auditorium features a dragon panel and chandelier reminiscent of the dragon caisson and Xuanyuan mirror found in the Forbidden City.[73]
