Consumers' pursuit of quality life will increase day by day. It will be difficult to retain users by simply satisfying functional needs.

For start-ups and growing companies, the "quality upgrade model" is the key to success. For traditional large companies, the "quality upgrade model" is the key to ensure that they are not replaced by new-era companies. The collapse of the empire is much faster than we imagined.
