It has a clean government, good public security, a free economic system and a sound rule of law.

Famous throughout the world.

On December 20, 1999, the Chinese government resumed the exercise of sovereignty over Macau.

After Macao returned to China, its economy grew rapidly and became more prosperous than before. It is a successful example of one country, two systems.

Macau is an international free port, one of the most densely populated areas in the world, and one of the four major gambling cities in the world.

Its famous light industry, tourism, hotel industry and entertainment venues have made Macau prosperous and become one of the most developed and wealthy regions in the world.

2. Shenzhou 5 takes off. The Shenzhou 5 manned spacecraft is the fifth in the "Shenzhou" series of spacecraft. It is the first manned spacecraft launched by China.

It was launched from the Jiuquan Satellite Launch Center at 9:00 on October 15, 2003, sending astronaut Yang Liwei and a Chinese flag with special significance into space. It returned at 6:23 on October 16, 2003.

This spacecraft marks China becoming the third country to send humans into space after the former Soviet Union (Russia) and the United States.

It marks another milestone in my country's aerospace technology.

3. China’s “Sky Eye” 500-meter Aperture Spherical Telescope (FAST), referred to as FAST, is located in the karst depression in Dawodang, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province.

The project is a major national science and technology infrastructure. The "Sky Eye" project consists of active reflector systems, feed support systems, measurement and control systems, receivers and terminals, and observation bases.

The 500-meter aperture spherical radio telescope is known as the "China Sky Eye". It was conceived by Chinese astronomer Nan Rendong in 1994. It took 22 years to build and was inaugurated on September 25, 2016.

It is built under the leadership of the National Astronomical Observatory of the Chinese Academy of Sciences, has my country's independent intellectual property rights, and is the world's largest single-aperture and most sensitive radio telescope.

The comprehensive performance is ten times that of the famous radio telescope Arecibo.

4. "Two bombs and one satellite" "Two bombs and one satellite" refer to atomic bombs, missiles, and artificial satellites.

"Two bombs" refers to atomic bombs and missiles, and "one star" refers to artificial satellites.

In recent years, "two bombs and one satellite" has also referred to missiles, nuclear bombs, and artificial satellites.

On November 5, 1960, China's first imitation missile was successfully launched. At 15:00 on October 16, 1964, China's first atomic bomb exploded successfully, making China the fifth country with atomic bombs.

At 8:00 a.m. on June 17, 1967, China's first hydrogen bomb air burst test was successful; at 21:00 on April 24, 1970, China's first artificial satellite was successfully launched, making China the fifth country to launch artificial satellites.

China's "two bombs and one satellite" are the glorious achievements created by the Chinese nation in the second half of the 20th century.

5. The aircraft carrier was successfully developed. The Liaoning aircraft carrier (codename: Type 001 aircraft carrier, hull number: 16, referred to as: Liaoning) is an aircraft carrier under the Chinese People's Liberation Army Navy that can carry fixed-wing aircraft. It is also China's first aircraft carrier in service.

aircraft carrier.

The predecessor of the Liaoning aircraft carrier is the Soviet Navy's Marshal Kuznetsov-class aircraft carrier sub-ship Varyag. In the mid-to-late 1980s, the Varyag encountered the disintegration of the Soviet Union when it was being built in Ukraine. The construction project was interrupted, and the completion rate was 68%.

.

In 1999, China purchased the Varyag and arrived at Dalian Port on March 4, 2002.

On April 26, 2005, the Chinese Navy began to continue construction and improvement.

The People's Liberation Army's goal is to modify and manufacture this unfinished aircraft carrier and use it for scientific research, experiments and training purposes.

On September 25, 2012, it was officially renamed Liaoning and delivered to the Chinese People's Liberation Army Navy.

In November 2013, the Liaoning ship sailed from Qingdao to the South China Sea to conduct a 47-day comprehensive maritime exercise. During this period, the Chinese Navy organized a large-scale ocean-going aircraft carrier battle group with the Liaoning aircraft carrier as the mainstay. The battle group consisted of nearly 20 ships of various types.

This is the largest maritime force concentration exercise by a single country in the Western Pacific since the end of the Cold War, except for the U.S. Navy. It also marks the beginning of the Liaoning aircraft carrier's maritime formation battle group capabilities.
