Couplets in Qiu Zu's Tomb

Recently, grandpa was grateful for the kindness of his parents and grandparents. He wanted to repair the ancestral grave and asked for a tombstone couplet of Sanfu. My great-great-grandfather's parents Long Yonggang and Zhu Chengxian are not buried together, so they need two couplets. My great-grandfather's surname is Long and Fu's family are buried together, so I need a couplet. Thank you.
