Introduction to Deepin and Software Management

Deepin (formerly known as Linux Deepin) is committed to providing a beautiful, user-friendly, secure, and reliable Linux distribution for users worldwide. The Deepin project was initiated in 2008 and released its first version under the name "Linux Deepin" in 2009. In April 2014, it was renamed "Deepin" and is often referred to as the "Deepin Operating System" in China. Deepin is an open-source operating system primarily based on the Linux kernel and focuses on the desktop environment. It features a clean and modern interface, a wide range of applications and tools, and can meet daily office, study, and entertainment needs.
