I watched ECHOES OF THE RAINBOW - cantonese movie last night.
Sandra Ng's motherly character kept saying, "Chou Yan, Chong Yu Sun"

"TO LIVE, YOU MUST BELIEVE".
During the darkest hour, she held on to this belief to fight off the despair that was mounting on her family.

Tragedy after another, she still kept repeating the quote like a mantra.

There was simply no other belief she could choose.
