During the 7th and 8th centuries, China experienced the height of its feudal society under the Tang Dynasty. This era, known as the Kaiyuan period, witnessed a highly developed social economy, a prosperous Silk Road, and a thriving population. People enjoyed a prosperous life during this time.

In this city-building game, you will delve into the urban economy of the Tang Dynasty. As a city builder, you must consider the needs of the people, allocate work efficiently, and engage in trade with other cities to ensure a stable urban financial income. You'll need to establish an efficient transportation system to coordinate the supply of goods and allocate limited resources effectively.

To defend your city, you must train a strong army. Carefully consider the financial capacity of the city when expanding the army, and focus on training elite forces to enhance the city's defense capabilities. Appointing capable generals will further enhance the combat effectiveness of your soldiers.

Building a famous palace from the Tang Dynasty is also a significant challenge in the game, as it requires substantial manpower and building materials. The game provides a realistic environment by simulating day and night cycles, as well as changing seasons. Each city you construct represents a real city from the Tang Dynasty, and historical events corresponding to the era, such as the Kaiyuan Prosperity and the An Shi Rebellion, will unfold.
