Seeing the old man scrimping to send his child to school — the love of parents everywhere.
Tips
culture
Attributed to a poem by Empress Dowager Cixi for her mother's 60th birthday. 可怜 here means 'pitiable / touching / deserving sympathy,' not 'pathetic.'
mistakes
可怜 does NOT mean 'pathetic' here. Think 'how touching' or 'how sympathetic' — a parent's love is often expressed as worry and sacrifice worth our compassion.
