吃醋是最明显的告白陪伴是最长情的表白
[chī cù shì zuì míng xiăn de gào bái péi bàn shì zuì zhăng qíng de biăo bái]
Translates to 'Jealousy is the clearest confession, companionship is the longest-lasting expression of love.' This implies that jealousy shows how deeply one cares for another, while long-term support is a profound form of expressing affection.
