On July 30, 2004, the State Postal Bureau issued its first asymmetrical perforated stamp in tnbute to the popular tale of how the Eight Immortals Crossed the Sea. The Eight Immortals are the most important figures in Chinese Taoist mythology. Each carried with them a magical object: a drum, a fan, a sword, a gourd, a bamboo flute, castanets, a basket of flowers and a lotus. Wherever they went they helped the weak and poor, punished evil-doers and encouraged people to do good. Immortality was their reward for such good deeds.
