Hongkong Post will unveil a set of four stamps entitled 'Chinese Idioms and Their Stories' on Thursday, when the series goes on display at the General Post Office in Central. The stamps, which will also be displayed at Tsim Sha Tsui, Tsuen Wan and Sha Tin central post offices, will be officially issued on June 15. The series features a special postmark illustrating the theme of traditional values, which will be date-stamped on the official first-day covers. The $1.40 stamp, 'Respect makes successful marriage', shows a shy couple raising cups towards each other in mutual respect. The illustration depicts a story from the Spring and Autumn Period (770-476BC), when Jiu Ji of the State of Jin saw on his travels a woman bringing her husband lunch while he worked in the fields. Jiu Ji was impressed by the courteousness of the couple, who respected each other like guests. The $2.40 stamp, 'Reading is always rewarding', depicts Emperor Taizong of the Song Dynasty (AD960-1279) surrounded by books and reading by lamplight. The emperor had a habit of reading every day despite his heavy administrative duties. 'Prepare for success', the $3 stamp, depicts Zu Ti, who later became a formidable general during the Eastern Jin Dynasty (AD317-420) and was renowned for his skills as a swordsman. Zu Ti was awakened by a cock's crow every morning and then woke up his close friend Liu Kun, with whom he shared the mission of protecting their country, to practise together with their swords. The $5 stamp, 'All in the same boat', depicts two men, Wu and Yue, whose hands are clenched together. The two were enemies during the Spring and Autumn Period, when a storm broke out as they travelled in the same boat. In distress, they put aside their hostility to help each sail through the storm. The moral of this story is that people should help and support each other in difficult times. 'These vivid and colourful stamps help to keep these important values alive and relevant in the 21st century,' Postmaster-General Joanna Choi Leung Yuen-mei said.
