On Friday, dozens gathered in Chinatown as the old Golden Star Radio unveiled a brand new neon sign.
Ron Tong's parents opened the radio station back in the 1930s, becoming the first Chinese-language radio broadcaster in the country.
"It was a void that needed to be filled. You know, there was no Chinese broadcasting," Tong said.
Throughout the years, Golden Star Radio became an institution in Chinatown, connecting thousands of new immigrants with a piece of their homeland.

But over the years, the radio station's iconic sign fell into disrepair and in the 1970s, the broadcasts stopped altogether.
Now, thanks to donations, the sign is officially lit again -- and on the same building still owned by Tong's family.
"It means a lot, because we're still remembered. Most of the population that listened, they're all gone. So you have to be 65+, minimum, to get it," Tong said.
But Golden Star Radio has meaning for more than just the Tong family. For many who grew up in this vibrant neighborhood, it's a piece of San Francisco and American history.
"For me, it means bridging the last generation to the new generation. And now the space is still being utilized. I think it's very meaningful," said lifelong Chinatown resident Amy Lee.

Local leaders, too, say preserving that intangible culture is critical, especially in an era of mass technology and rapid change.
"There are families who passed down this memory, who know about this. But then there are others who don't, who need to learn about this. And it's a physical sign. It's a physical representation to tell that story," said Supervisor Danny Sauter.
And even though they're no longer here to see the new sign themselves, Tong believes his parents would be prouder than ever.
"I'd think they'd be happy to see the sign. It's 40 years of dedication, commitment to the community. It's a great tribute," he said.
