Flag of Tseng

The flag of the Tseng Republic (曾島民國國旗) is a horizontal tricolour of blue, white, and red.

History
The modern flag of the Tseng Republic was designed by Gerald Wong, although variants of this flag has been used since the 11th century, during the Five Kingdoms Era. It consisted of a horizontal tricolour of solid blue, white, and red. On July 17, 1946, it became the unofficial flag, and on August 8, that flag was adopted as Tseng's official flag.

During the Tsengian military junta of 1968, the blue was a light sky blue.

In the last days of the Luanzheng Era, when the Twenty-Four Liberators raised the Tsengian flag on the Presidential House, the flag on the building was accidently painted a lighter blue than the 1946-68 flag, and as a result it stuck and on December 31, 1968, was adopted as the official flag of Tseng.

Protocol
The flag's ratio is 2:3, although 1:2 proportions are also used.

The flag is always flown horizontally from public buildings, private homes, businesses, ships, town squares, or during official ceremonies. Government buildings must fly the flag 24 hours and it must be properly lit. The Flag of Tseng must never be soiled or damaged in any way, shape, or form.

If the flag is there will be penalties if caught, ranging from a fine or life imprisonment.

Similar flags
The Tseng flag is similar to the Dutch and Luxembourg flags, however, it is simply just a coincidence. The only difference is that the red and blue are switched around and the blue is darker (lighter for the Dutch flag). However, it has not stopped people from advocating the change of the flag.

Also, until 1992, the Yugoslavian flag was almost identitical to the Tseng flag with the exception of the shade of blue and red star in the centre.
