Because the walls of the Forbidden City are red, wearing red to take pictures will contrast colors.

The Forbidden City is an important heritage of China's history and culture, so the dress requirements for visitors are strict. It is hoped that tourists will dress appropriately and respect history and culture to show their respect for the Forbidden City.

In addition, the Forbidden City also stipulated other dress requirements, such as the prohibition of wearing slippers, short skirts, shorts, backless, waist-exposed and other inappropriate clothes. Visitors should wear decent, neat and comfortable clothes, and don't wear exposed or exaggerated clothes, so as to observe the rules and etiquette of the Forbidden City and facilitate the visit.

The construction of the Forbidden City in Beijing began in the fourth year of Yongle (1406), based on the Forbidden City in Nanjing, and was completed in the eighteenth year of Yongle (1420), becoming the palace of twenty-four emperors in Ming and Qing dynasties.

"Wei Zi, Ziyuan, Zigong and so on have become synonymous with the Forbidden City. Because the feudal palace was forbidden in ancient times, ordinary people could not enter it, so it was called "Purple Forbidden".

In the early Ming Dynasty, it was called "Imperial City" together with the outer forbidden wall, but it was different from the outer forbidden wall in the middle and late Ming Dynasty, that is, Miyagi was called "Forbidden City" and the outer forbidden wall was called "Imperial City".
