Cherish a sunny day revolves around the family of Mrs. Nga who sells vermicelli noodles and lives with her unintelligent brother and three daughters. As a widowed woman in her 60s, her mind is still not at peace when her three daughters, although grown up, are always full of problems in life. Although she is talkative, grumpy, hot-tempered, but with her sacrifice and boundless love, she is always a firm fulcrum for her brother and daughters.
