Something happened to Baghdad next.
Emperor Shang Zhang decided to make it capital. When he came to Baghdad, he thought it was a complete terrible mess. He found plans on Persian Baghdad and Muslim Baghdad. He was then to combine them together to make a great city.
Shang Zhang repaired Baghdad as it was during Sassanian and Arabian times, and swirled Roman culture. Baghdad became a capital city that is the most enormous, magnificent, splendid, wealthiest, fortified, and the greatest city in the world. It had 40 million people. It is very huge because the city covered all of Mesopotamia and Sumer. It had magnificent and splendid buildings, and has a bunch of 55 forums at the middle as with the Imperial Palace. It had huge harbors and series of canals. Baghdad was a tropical paradise. It had a lot of palm trees and has a firefighter and police force to look after the city. And yes, as with every city, there were poor and rich. Everyone speaks Chinese, Japanese, barbarian languages, and Indian, but in the empire, but rarely, other worldwide languages. Their culture is very advanced, and trading happens more there than anywhere else. With thick walls, fortified with watchtowers, gates, forts and super fire-shot trebuchets made land of sea invasions difficult. Gunpowder in using it for fireworks and made a technique of the fire shot with cannons, bombs, and explosions. It boasted a sewer system, and organized social service in hospitals, homes, and orphanages. Ships crowded the city's harbors. Luxuries come from all over the world. People without jobs are given, such as sweeping the streets, and weeding public gardens. The city's streets either narrow of wide, grand and broad, straight or twisting. People, camels, mule trains, horses, elephants, soldiers, merchants, peasants, water sellers, sweetmeat sellers, porters, beggars, raged children, barefooted slaves, stray dogs and cats, pets, priests, carriages, and litters all crowd the streets. Many luxuries items, like ivory, pottery, skins, coats, cloth, umbrellas, fans, camels, compasses and other navigation tools, myrrh, incense, slaves, chariots, bowls, crowns, jade, gems, shields, art, paintings, porcelain, tea, lacquer, fruits, timber, cushions, cloth, beds, weights, scales, pets, livestock, models, vases, special flowers, silver, mosaics, silks, fur, perfumes, rum, gold, furniture, cast-iron products, decorative boxes, cotton, pearls, cosmetics, carpets, dyes, trays, glass products, small bottles, necklaces, coral, asbestos, foods, swift large horses, Samian ware (ware from Rome, starting to make them), fabulous and wealthy jewelry, rich dining utensils, rum, vegetables, metals, swords, plants, musical instruments, elephants, slaves, medicine herbs, Indian china, ornaments, decorating supplies, spices, precious and colored stones, and other luxuries items and goods fled in Baghdad's and its empire's markets. Statues were very lifelike. Everyone attended circuses, theaters, and amphitheaters. They were one of the many recreations that made the Chinese happy. All roads and trade routes lead to Baghdad. Public works were always made, and it has expanded a lot as the population grew. Its ports are centers of warship building, seafood produce, and centers of trading. Canals were water streets where ships drove on, and many monuments are found. There were many arenas where battleships fought, and there were many buildings that could stand on the water. Ships guard and control the waters around the port. Irrigation ditches were built at the ports in swampy areas to deliver to farms to control the water level. Chinese engineers had made a filter to turn the water cleaner, and most of the water is delivered the fountains and waterfalls that flow to the canals at the port. Chinese refer the ports as paradises. A trillion temples and shrines are dotted in the city. Baghdad also produces everything in their economy list. Trade always flourished in the empire. There was many food supplies stockpiled in the city. To the Romans, there was no special cargo than grain. It was the main food supply for making bread, pasta, cereals, and crackers. In this city, what's so strange about is that many structures, and there were terraces over terraces, streets above streets, and then zigzag roads and huge flights of steps bordered (and are also found there) with orange and lemon trees, roof-gardens, balconies, deep archways, pillared colonnades, spires, battlements, minarets, and pinnacles. Many government buildings house laws, records, and orders. A trillion temples and shrines are dotted in the city. Chinese guards as well as the emperor, they defend city against invaders. A huge ring surrounded the city, packed with traps to kill and crush the enemy army. The Circle of Zheng, a circle that holds military meetings on what to do in the base, plans on the battles in case they happen. The forts were even located in the city itself. Everyday, people could see soldiers as a magnificent sight. Generals and their army march across the city. Blacksmiths had done the work on improving the army and finding new technologies. Both the senate and the emperor gave orders to the Praetorian Guards. With guards all over the place, invasion was always difficult. The city still expanded a lot. However, in 1200, the empire split, and Baghdad became a part of a new empire.
