三寸季年不忘卿七堇年华不负君
[sān cùn jì nián bù wàng qīng qī jĭn nián huá bù fù jūn]
A complex and poetic phrase translating loosely to 'Through three inches of seasons we won’t forget you; through seven violets (jinxing) years we won’t let you down.' This suggests deep and long-lasting affection or loyalty across time and changing conditions.
