简介：1999 can be said to be a particularly unforgettable year, with many unforgettable major events happening. NATO and the United States brazenly bombed the Chinese Embassy in Yugoslavia, resulting in the death of four Chinese citizens. This is something that has already happened. There are major events that have not happened yet, such as the grand military parade celebrating the 50th anniversary of the founding of the People's Republic of China and the smooth return of Macau.
