I purchased this fine piece of analog pixel art (cross-stitch embroidery) from a Carousell seller named Jess and had it framed by the craftsmen at Barakkath Frame Maker in Chinatown. I’m delighted with it!
The Chinese characters are:
sōng hè yán nián
pine crane prolong year
Pines and cranes are symbols of longevity. The flowers are a kind of peony (tree peonies, moutans, or mudan). They are medicinal as well as ornamental.
See close-up below.
