The poster at left shows infants carrying a jade object. It was made soon after the overthrow of the Qing Emperors in 1911. The jade object is a ju-i, a sceptre carried by monarchs, symbolizing power. The phrase "holding the ju-i" means taking responsibility. So when the toddlers, symbolizing hope, hold the sceptre, the message is "celebrate the new Republic". A hundred years ago, illiteracy was common, so learning was spread through folk arts like this, with symbolic meaning. New Year posters are a kind of narrative tracking the dreams of ordinary people, mostly poor and disadvantaged. Fat kids mean there won't be famine, multiple babies mean that some, at least, will survive. When little girls are depicted, as well as, or in place of boys, the message is the New Woman, a symbol of modern China and equal rights. Later still, the infants are shown holding cars, spaceships and radios, new symbols of modernization and prosperity. Of course there are propaganda elements, but for ordinary people such things meant hope. Nowadays people are so materialistic that they forget how things might have felt from the perspective of the poor.
Sadly this poster must have been made before the Red Guards demanded the abolition of all culture. "Smash the Olds" was their slogan, the denial of the past, and all learning, to serve the political agendas of their present. "Alt facts" before the term was invented. Some things don't change, east or west.
