South Africa is the only country in the world with three capitals, namely - "Pretoria, the administrative capital, the seat of the central government of South Africa, with a population of 2.35 million, Cape Town, the legislative capital, the seat of the South African Parliament, the second largest city and an important port in the country, located in the southwestern end, the junction of important international shipping routes, with a population of 3.5 million, and the judicial capital of Burundi, the national judiciary. Located in Pretoria with a population of 750,000, the Presidential Palace of South Africa is a Greek-style granite building with an arc-shaped center and a bell tower on each side. The office rooms are on both sides of the bell tower (the Presidential Office is in the left building facing the Presidential Palace). The two bell towers represent the Netherlands, the United Kingdom and a memorial across the road from the Presidential Palace. The monument, established in 1938, commemorates South African soldiers who died in the two world wars. During the two world wars, there were no wars on South Africa's mainland, but as a Commonwealth country, South Africa sent troops to participate in the war. There are dozens of steps under the monument. There is a huge statue of Nelson Mandela, the first black president of South Africa. He stretched his arms and left legs forward and made a hug gesture. South Africa is the rainbow country. This is Mandela's ideal. South Africa was originally the home of black people. For historical reasons, there are many races, nationalities and colors of people gathered here. No. People of the same race and colour will live peacefully and equally under the same blue sky, like a rainbow, which is the country of rainbows. Mandela fought for him all his life. He was the greatest black leader. There are 60,000 street trees imported from Rio de Janeiro, Brazil, in Pretoria. The trees are big. They have blue-purple flowers in spring and long leaves behind them. The blooming period is about a week (South Africa's spring is Beijing's autumn, and the blue flowers blossom in early October every year). In a street not far from the presidential palace, there are blue flowers blooming on both sides of the street. It's suffocating. It's just blooming. It's only a week old.
