Stamp commemorates Shenzhou V's historic journey Astronaut Yang Liwei will be officially invited to Hong Kong next month to mark the historic and successful launch of China's first manned space mission. The government has also issued a special stamp to commemorate the occasion. A Leisure and Cultural Services Department spokeswoman yesterday said the invitation for Lieutenant-Colonel Yang would be sent to the central government. She said the astronaut's visit would be coupled with activities next month organised with other science and technology promotion bodies from the mainland and Hong Kong. Chief Executive Tung Chee-hwa yesterday wrote to President Hu Jintao, Central Military Commission chairman Jiang Zemin, and Premier Wen Jiabao, congratulating them on the successful mission. 'Following the successful launch and return of this manned spacecraft, which has been designed and developed by our country, our manned spacecraft technology has entered an important era. The 6.8 million people of Hong Kong are overjoyed, jubilant and very much encouraged to hear the news,' Mr Tung said. A survey carried out by the Hong Kong Federation of Youth Groups on Wednesday found 70 per cent of 500 respondents aged 15 to 34 said their pride in China had risen after the successful launch. About 42 per cent believed the launch had also lifted the international standing of the country. To mark the successful launch of Shenzhou V, Hong Kong, the mainland and Macau yesterday jointly issued a special stamp package. The announcement, which came after the successful landing of Shenzhou V yesterday morning, was the third time China and the two special administrative regions co-issued stamps to commemorate an important national event. Allan Chiang Yam-wang, Hong Kong's Postmaster-General, said China Post had invited Hongkong Post and Macau Post to discuss the stamp issue in January. The stamps were printed two months ago, awaiting the historic issue. 'We have been liaising for weeks to decide when to make the announcement. It was not until 7am today that we were notified by our mainland counterpart that we could release the stamps for sale,' he said. The package consists of three pairs of stamps designed by mainland artists featuring various themes. All the stamps were printed with reddish fluorescent ink, which glows when viewed under ultraviolet light.
