戚时问安书
[qī shí wèn ān shū]
In classical Chinese literature, 'Qī shí wèn ān shū' can be translated as 'letter asking after someone named Qī timely.' This might symbolize respect for and care about a loved one called 'Qī,' perhaps a person of importance like parents, friends or lovers in the owner's heart, indicating a sense of warmth and affection.
