How to blink LEDs to display binary codes using an 8051 microcontroller?

Many CS or EE undergrads or enthusiasts try to deep dive into embedded software or systems on their own. Though there are many tutorials dedicated to the basics of microcontrollers and programming, few are dedicated to simple projects using assembly on the 8051 microcontrollers. 8051 family is one of the beginner-friendly easy-to-learn microcontrollers, and here I will be showing a simple blinking-led project to get you started with 8051.
