The name of the store is equivalent to the signboard of the store. Ancient people often put gold foil on the name of the store, calling it a gold signboard, which also became a means of showing off, suggesting that the business in the store was very prosperous. The purpose of opening a shop is to make a profit. Bosses are naturally happier when their business is booming, so they can bring gold characters when choosing a store name, which also means they can make a fortune.
