黑米保护的蛋叫小黑
[hēi mĭ băo hù de dàn jiào xiăo hēi]
It means 'The egg protected by black rice is called little black'. Here, black rice stands symbolically for something providing protection, nurturing care. Hence, 'little black' (the protected object) could represent a newborn cherished and raised carefully, possibly indicating a loving guardian-ward bond.
