Why can Vietnam's high imitation version of the Forbidden City become a world heritage?

Because this Forbidden City is really an ancient building, although it is not as good as the Forbidden City in China, it is also an ancient building with Vietnamese local characteristics, which is also of great significance, so it can become a world heritage. This highly imitated Forbidden City is indeed very similar to the Forbidden City in China. Its name is Hue Imperial City, and the locals also call it the Forbidden City.

However, Hue Imperial City was really influenced by China culture. In other words, it is a miniature version of the Forbidden City in China. The architectural style of the Imperial City is basically the same as that of the Forbidden City in China, and even the archway in front is almost the same as that of the Forbidden City. Hue Imperial City refers to the architectural design of the Forbidden City in China. The overall shape is square, a moat is built around the imperial city for protection, and there are also four gates. Hue imperial city also has the difference between inner city and outer city, in which the Forbidden City is the innermost place, which is the residence of the emperor and empresses.

So Hue Imperial City is really like the Forbidden City in China. Many representative buildings and locations are also modeled after the Forbidden City in China. Vietnamese locals said that this Hue Imperial City was actually related to the completion of the Forbidden City in Beijing.

At that time, when the Forbidden City was built, there was a shortage of manpower, so some craftsmen were deployed to help with the construction. Jiaotuo is actually Vietnam today. Later, the craftsmen who crossed their toes returned to their own country, and the king asked them to build a Forbidden City with the same structure as Beijing.
