December 20 marks the 20^th anniversary of Macao's return to the motherland. Over the past 20 years, the government of the Macao Special Administrative Region (Macao SAR) has united people from all walks of life, fully understood and implemented the "one country, two systems" policy, firmly maintained the authority of the Constitution of the nation and the Basic Law of Macao, inherited and carried forward the core values of loving the motherland and loving Macao. As a result, Macao’s economy has grown rapidly, its people's livelihoods have improved steadily and the society has maintained stable and harmonious, showing the world the successful practice of "one country, two systems" with the characteristics of Macao. To mark this significant occasion, China Post issued a set of 3 commemorative stamps on the same day.

In addition, a 110 mm ×150 mm souvenir sheet with the same theme was jointly printed by the two parties, which contains 3 stamps of China Post and 3 stamps of Macao Post and Telecommunications.

The first stamp features "carrying forward the value of loving the motherland and loving Macao from generation to generation". In the center of the design is  the shimmering lotus sculpture, around which are Macao people on the Golden Lotus Square waving the national flag of China and the flag of Macao SAR. The design highlights the festive atmosphere and conveys the love of the compatriots for Macao and the motherland and their sense of identity and pride as part of the Chinese nation.

The second stamp features "a harmonious inclusiveness of Chinese and Western cultures". In the center of the picture is the dancing dragon performed in front of the conference pavilion. The background includes the Ruins of Saint Paul’s Cathedral, A-Mar Temple (or MazuTemple), Guia Lighthouse, Taipa Houses of the Macanese Living Museum and other buildings, showing the multicultural characteristics of Macao.

The third stamp features "prosperity and development of urban construction". The Hong Kong-Zhuhai-Macao Bridge is the focus of the picture. Behind it, the Sai Van Bridge which was constructed after the return of Macao to the motherland extends from the right to the left. The two bridges reflect the urban construction and development of Macao, symbolizing that Macao beats with the pulse of the new era after return. Behind the bridges are the new campus at Hengqin of the University of Macau and the Hengqin · Macau Youth Entrepreneurship Valley, conveying the idea that Macao has integrated into the national development, actively joined the regional cooperation strategy, and jointly promoted the construction of the Guangdong-Hong Kong-Macao Greater Bay Area.

The stamps were designed by Han Binghua, a famous designer from Hong Kong, and printed by Beijing Stamp Factory.

On December 20, to celebrate the 20^th anniversary of Macao's return to the motherland, 10 sets of Macao theme stamps issued by China Post and 182 sets of stamps issued by Macao in the past 20 years since its return to the motherland will be displayed on a special stamp exhibition held by China National Post and Postage Stamp Museum, displaying the historical and cultural landscapes and the achievements in Macao’s development of this period.

It is known to us that in the 20 years since its return, Macao Post and Telecommunications has issued stamps with the name "Macao, China". Macao stamps not only inherit the long and splendid Chinese traditional culture, highlighting the consistency of the regional culture with the motherland, but also have the unique charm of the integration of Chinese and Western cultures. Macao stamps are increasingly favored by collectors at home and abroad because of their national characteristics and inclusiveness.
