Chang 'an was the capital of the Western Han Dynasty and Luoyang was the capital of the Eastern Han Dynasty. The Silk Road originated in the period of Emperor Wu of the Western Han Dynasty, and it was a famous Zhang Qian's mission to the Western Regions. But in the subsequent development, the Western Han Dynasty did not develop to Rome. At that time, there was almost no intersection between the Roman Empire and the Western Han Dynasty. It is only said that the Silk Road was opened in the Western Han Dynasty, so the idea of East Chang 'an and North Rome is a preconceived idea. Xi 'an, known as Chang 'an in ancient times, is one of the four world-famous ancient civilizations, ranking first among the four ancient capitals in China. It is the capital with the longest history, the most dynasties and the greatest influence in China. Known as the "ancient capital of the 13th Dynasty", it is the birthplace of Chinese civilization, the cradle of the Chinese nation and an outstanding representative of Chinese culture.

Chang 'an, the capital of the Western Han Dynasty, was founded by Zhang Qian when Emperor Wu of the Han Dynasty opened up the ancient Silk Road. The exquisite silk products of the Han Dynasty were transported to Rome along the Silk Road and then to Western Europe. Later, China porcelain caused a sensation in Europe and was used and collected by European nobles. At that time, the Silk Road was a major channel for communication between the East and the West, and materials from the East and the West were exchanged through this road. At the end of the Western Han Dynasty, class conflicts led to constant wars, and the Silk Road almost stopped at this time. It was not until the establishment of the Eastern Han Dynasty that the Silk Road slowly developed. As we all know, the famous Ban Chao not only recovered during this period, but also made longer-term progress than before. However, after the demise of the Eastern Han Dynasty, the Silk Road seemed to experience another low tide and became a popular route for businessmen until the prosperity of Sui and Tang Dynasties.

The Silk Road in a broad sense is divided into the Silk Road on land and the Silk Road on the sea. The overland Silk Road originated from the overland passage of Zhang Qian, the Emperor of the Western Han Dynasty, who was sent to the western regions. It started from the capital Chang 'an (now Xi 'an), passed through Gansu and Xinjiang, reached Central Asia and West Asia, and connected Mediterranean countries. Its original function was to transport silk produced in ancient China. The Western Roman Empire perished in 476 AD. In China, it was the period of Emperor Xiaowen in the Southern and Northern Dynasties, but it has not moved its capital so far.

The Roman Empire rose in 27 BC, just like the Western Han Dynasty, the Eastern Han Dynasty, the Three Kingdoms, the Western Jin Dynasty and the Northern Wei Dynasty in China. There is no doubt that the center of China in this period was Luoyang, not Chang 'an. To sum up, the Silk Road originated in the Western Han Dynasty (Chang 'an), flourished in the Eastern Han Dynasty (Luoyang) and flourished in the Tang Dynasty (Chang 'an). Although it is also true that Luoyang is the starting point, Chang 'an is more influential, which is why we should start from Chang 'an. In fact, neither Luoyang nor Chang 'an can deny the fundamental fact that the Silk Road began in China. The struggle between the two can only be said to be a contradiction among the people, and it is better not to be taken away by foreigners.
