In the 7th century, the strength of the Tang Dynasty reached its peak, and many surrounding ethnic minority feudal states called themselves Chennagong and honored the emperor of the Central Plains as "Heavenly Khan". The Tang Dynasty Han Chinese historical records that there was a Tubo Dynasty on the Qinghai-Tibet Plateau at that time, and the Tang Emperor repeatedly married the princess to Zampu of Tubo, bringing Tang culture to Tubo and promoting the prosperity of the Tubo region. In later generations, a tribe of Tubo developed into a neighbor of China.
The country is Bhutan. Bhutan is one of the least developed countries in the world and the last country in the world to open the Internet, and the real independence of the historical Bhutan began with the Qing Dynasty, and during the Yuan Dynasty, Bhutan was also managed by the Central Plains Dynasty Xuanzheng Yuan. After breaking free from modern colonial history, in 1907 Uyan Wangchuk established the Kingdom of Bhutan.
The kings of Bhutan are hereditary, similar to the "family world" of the ancient Chinese feudal dynasty. Many people may think that Bhutan is backward, and everyone's happiness index is certainly not high, but the actual situation is not so, Bhutan is actually one of the countries with the highest happiness index in the world, where people all have their own beliefs, some believe in Tibetan Buddhism, and some believe in Bhutanese primitiveism.
For some historical reasons, the life customs of the Bhutanese people and even the national flag can find some similarities with China, such as the people there who like hot and spicy food, love to eat chili peppers to the same extent as the Sichuan people, and they also eat traditional Chinese food dumplings. For example, the flag of Bhutan has a historical relationship with the former Great Qing Dragon Flag.
Among the flags of countries around the world, the flag of Bhutan is the only one that uses the dragon motif. As we all know, the dragon is the spiritual totem of the Chinese nation, and the ancient Chinese emperors all regarded themselves as the "True Dragon Heavenly Son", and Chinese in addition to calling themselves "descendants of Yanhuang", they also liked to say that they were "descendants of the dragon". Therefore, when the Qing Dynasty selected the national flag that year, it also used the dragon pattern.
After the failure of the Taiping Heavenly Kingdom Movement, the Qing Dynasty began to set up a marine fleet, according to the international practice at that time, the warship should fly its own national flag, so the Qing court made a yellow background, blue dragon, on the top of the red sun pattern of the pennant flag; in 1881, for convenience considerations, Li Hongzhang wrote a report, applying for the pennant to be changed to a rectangular flag, but 7 years later, the Qing Dynasty officially established the rectangular dragon flag as the national flag of the Qing Dynasty.
It's just that the dragon flag of the Qing Dynasty has 5 claws, and the dragon flag of Bhutan has 4 claws. This is because the historical Bhutan once enshrined the Qing Dynasty as the suzerainty, and when designing the dragon flag to indicate the identity of the clan, it did not use a 5-clawed dragon and lost one claw. The dragon with 5 claws is dedicated to the Chinese emperor, but the Bhutanese also like dragons, calling their country "cloud China" and "the country of the dragon".
Bhutan is the only neighboring country around China that has not established diplomatic relations with China, but many Chinese are very interested in Bhutan's exoticism, such as the star Liu Jialing once chose to hold a wedding in Bhutan because she longed for Bhutan's Buddhist culture and liked Bhutan's quiet and peaceful living atmosphere, which also made Bhutan once become the focus of attention.
