Cranes have been traditionally used as a vehicle of the gods and they symbolize longevity along with pine trees. The name of these celestial animals also share similar pronunciation. Cranes are graceful in form and are popular among the Chinese. They are the favourite subjects of Au Ho-Nien. Placed at the front are a pair of cranes, one singing, one resting, independent to each other. Background shows dense old pine trees, highlighting the cranes against the dark green background. The old pines were flourishing in their old age, enhancing the message of longevity. This work was painted by Au Ho-Nien in the spring of 1971, later composed the title for Mr Xieqing to celebrate his 72th birthday.
