Twins Chirri & Chirra are pedalling on their bicycles when they find a cave:

 

“Let’s take a look, Chirri.”
“Yes let’s go, Chirra.”

 

With those opening words, the twins in their matching white dresses (only a blue pocket differentiates Chirra from Chirri’s red pocket) ride their bikes into a tunnel, headlights illuminating the path ahead. They arrive under the sea. “Oh,” the rosy-cheeked twins say as they pedal in the water, surrounded by fish, coral and algae.

Rao Pingru and Mao Meitang married in Nanchang in 1948, when China was still dominated by rhythms and rituals lingering from imperial days. They stayed married through the Mao years, despite being separated for over two decades; in 1958, Pingru, was sent off for “Reeducation Through Labor”. His crime? He’d once served in the Kuomintang army. Their marriage ended in 2008, with Meitang’s death from kidney failure.
