书一封旧长信落一尘邮戳印
[shū yī fēng jiù zhăng xìn luò yī chén yóu chuō yìn]
'Seal an old, lengthy letter with a dust-laden postmark' poetically captures nostalgia through the act of sealing a handwritten letter from times past. A postmark that has traveled through time implies messages bridging distances between loved ones or reflecting on past communication methods.
