Mr. Fu and two scientists from the Aerospace Academy finished talking about things and came to his usual room with crutches, he suffered too many sins when he was young, and he worked day and night after entering the Aerospace Academy, and now he is not good at walking when he is old, even if he has to use crutches at home.

Li Jinnian was closing his eyes to recuperate, and when he heard the sound of the sliding door, he opened his eyes suddenly, and quickly got up.

"Slow down." Helping the old gentleman into the house, he whispered, and sat down with his grandfather, who was still gray-haired and not idle, "You are old, it is better to worry less about the affairs of the aerospace institute, so as not to overwhelm your body." ”

Facing his only grandson, Mr. Fu patted the back of his hand and said kindly: "I didn't worry about it, I just chatted occasionally." This person, once you are idle, if your brain is not working well, it will rust, so it is better to move more while your brain can still move. ”

The old gentleman who sat down saw at a glance the album on the low table, after a long time, the corners and corners of the album were yellow, although there was turbidity but still full of wisdom eyes fell on the album, the thin hand trembled and stroked the cover of the album, and the face of the old age spot had a faint but indissoluble sadness.

"Ever since your grandmother died, I haven't looked at it very much." The old gentleman sighed softly, and the album contained the memories of his life, as well as the sadness that he could not erase in this life.

Born in a wealthy family, even if he later stayed in the United States with a housekeeper and two servants to serve, he was tortured in order to come back to serve the motherland and his wife, and almost died under the bullets of the United States several times.

When they finally returned to China, they were forced to leave the space institute to live an inhuman life, and between the ages of 28 and 35, he and his wife died one after another, and tasted the sorrow of the world.

Fu Lao Zu enjoyed too much, and all the retribution of the ancestor should be on his children, and several times he and his wife wanted to take a hemp rope and tie it on the tree, a set of necks, it was better to go.

Thinking that their motherland was in dire straits, there were no aerospace, missiles, or satellites, and that the backwardness of the big country made them unbearable to leave like this, and they hugged their heads and cried several times, and wiped away their tears after crying, and the two couples continued to draw various drawings silently by themselves, and lived underground to complete the most rudimentary experiments with the simplest materials.

The old gentleman who opened the photo album fell on the photo of his wife who stayed in time, and said to Li Jinnian with a smile: "When your grandmother was young, she was a beauty within a radius of ten miles, and those who asked to marry could be lined up at the gate of Yangzhou City. ”

Recalling his wife, the smile on the old gentleman's face was very soft, and there was a little bit of water flashing in his wise eyes, "Your mother looks like your grandmother, and you follow your grandmother." ”

"Don't know the fireworks in the world? Grandfather, are you kidding me? Li Jinnian was afraid of making the old man too sad, and it was rare to joke with himself, "If I don't know the fireworks in the world, then you are worried, I am afraid that I will become a monk." ”

The old gentleman laughed, "You are not much different from a monk now, you have a cold face when you are young, whose girl sees you, and you must not be frightened?" ”

"When your mother was alive, she often said to me that it is not a good thing to be young and old, and I am afraid that you will be too cold and easy to suffer. Your grandmother and I were worried, but when I saw your cleverness later, I realized that they were unnecessary worries. ”
