There are two things yeye 爺爺 (my grandpa) always feels proud of. First, he served as an engineer in the air force of China in 1950s and worked with the engineers of the former USSR. Second, he has me as his granddaughter. At the age of 85, he was diagnosed with terminal pancreatic cancer. He could no longer fix the engine of a military aircraft, but he still has his granddaughter with him through his final days.
