The steel flowers in the United Nations Square, built in 2002, stainless steel welding, 23 meters high, it is said that it opened during the day and closed at night. There are 4 days in the year that are not closed, that is, the National Day on May 25, the Spring Festival on September 21, Christmas Eve on December 24 and December 31, but some people say that, Because the designer died, the company under construction collapsed, and signed a 25-year confidentiality agreement, so people later did not know the way of steel flower closing, so as not to cause greater losses, it has always been open. As for whether it is true, I am not very clear.
