RUFF is the first government-approved MMA organization in China, which is committed to building MMA culture and hosting world-class MMA events in China. We cooperate with the Wushu Association of the State General Administration of Sport to provide opportunities for top MMA athletes in China to show their talents, and at the same time provide wonderful legal fights and wonderful entertainment programs for domestic audiences.

Raspberry Pi (Chinese name is "Raspberry Pie", abbreviated as RPi, or RasPi/RPI) is designed for learning computer programming education. It is just a microcomputer the size of a credit card, and its system is based on Linux. It is a microcomputer motherboard based on ARM, with SD/MicroSD card as memory hard disk. There are 1/2/4 USB interface and a1100 Ethernet interface around the card motherboard (type A has no network port), which can connect keyboard, mouse and network cable, as well as a TV output interface for video analog signals and an HDMI high-definition video output interface. All the above components are integrated on a motherboard only slightly larger than a credit card, which has all the basic functions of a PC. You can perform many functions, such as spreadsheets, word processing, playing games, playing high-definition videos and so on, just by connecting the TV and keyboard. Raspberry pie B only provides computer board, no memory, power supply, keyboard, chassis and connection.
