As a group of people who have witnessed the rapid evolution of technology, Generation z has been associated with the technological Internet since they were sensible, and they are called "digital natives". They spend half of their lives online socializing, entertaining, and studying. As a result, they are more dependent on the convenience brought by the Internet, but lack of communication in real life. And this is a kind of “noisy solitude”. The central idea expressed in this collage is that everyone is an island. Generation z seems to know each other in such an isolated life just by connecting with network cables, but in fact there is an invisible barrier between them. The world of the Internet is as colorful as it is. But divorced from many real-life mediums, everyone seems not so real, like a face with a mask. They want to break through this barrier, but due to various factors affecting their personality and behavior, they are "false happy"

As survivors of war, the baby boomers or Generation X forged the bonds of their generation in flesh and blood. The mood of baby boomers in different countries is different because of the specific circumstances in different countries. But in the same context(the coming of peace time), countries are having their own baby boom. Take China's baby boomers as an example. After winning the war, the Chinese people fought fiercely for the construction of their country, which also became their common bond. At that time, the Chinese people were used to huddling together for warmth, waving red flags and forging a new country with blood and flesh. As a result, China's baby boomers are highly connected. However, for them, the road is not smooth sailing. In the seemingly hopeful future, there are still many "clouds" hanging over their heads. Either natural or man-made. But it didn't break the bond between people(the branches was been bent). Today's baby boomers are still eager to connect with people and endure the loneliness of the Internet(blocked by bubbles).

The biggest difference between Generation z and the baby boomers is the difference in the way of communication, which creates a generational gap that is difficult to bridge. Virtual and real ways of communication are complementary to some extent, but how to eliminate invisible barriers between people is something we need to solve through the means of design. Today Gen z and Baby boomers are at the opposite ends of the timeline. Although they all live in the same environment and appear to be closely related (the closely related balls), the gap between the two generations is actually invisible, which creates a severe split between the two generations. Gen z stands at the top of technology and generation, using a form of communication that only they can understand. It seems that we have been ignoring the feelings of older people (baby boomers), resulting in older people only socializing in ways that they can only understand. As is shown in the collage, the "line" walking above seems to coincide with the "streamline" below, but it never intersects.
