"Many people left comments, saying that the videos reminded them of their own grandparents," Wu said. "Some people asked me about the details so they could do the same for the elders around them."

Wu was glad that he could help others and make positive impacts. "It's like a relay of kindness."

Wu also made a special short "film" for his grandmother, of her chatting with friends, doing farm work, and household chores.

"When I first showed her this video, I was quite nervous," he said.

But Wu's grandmother turned out to be really fond of the "film". She even invited her friends to watch it, which Wu displayed for them with a projector.

"She was laughing when she saw herself working in the field and went into silence when she saw the close-ups that showed her wrinkles," Wu said.

"I wonder what was going through her mind in the four minutes."

Although the short video may not fit the common definition of a "film", Wu felt it captured the essence of his grandmother's life, and, most importantly, she loved it.

This experience has taught Wu to appreciate the time spent with his family, and he sincerely hopes that everyone can devote more time to their elderly loved ones.

He also wishes he could do more to help preserve the memories of the elders in the village.

"I will continue to focus on rural areas like my village and perhaps go beyond to create more changes," Wu said.
