What does Unicom mean by 3 trillion happy families?

"China Unicom's 3 Gigabit Happiness Billion" is the advertising slogan launched by China Unicom, aiming to show that its ultra-high-speed broadband network service can bring users a happy life. Among them, "3 Gigabit" means that the bandwidth rate of its broadband network can reach 3000 megabits per second, with extremely high download and upload speed. This ultra-high-speed network allows users to load and download large-capacity data files, such as high-definition videos and online games, so as to improve users' network experience and use efficiency. This is also a business innovation launched by China Unicom, hoping to attract more users and increase market share by providing high-quality services. Through such vivid propaganda words as "Three Huge Billions of Happiness", more people will know about Unicom's high-speed network service and attract more users to buy its products and services.
