What are the legends of Jiang Ziya, Guiguzi and Zhuge Liang?

When Zhuge Liang was young, he had the famous "Longzhong Dui", which analyzed the world form for Liu Bei and described the strategic vision for Liu Bei. When he was young, he became a great strategist of Liu Bei, and made great contributions to the coexistence of the three kingdoms and Shu. He defeated Cao Cao in the case of great disparity in strength in Chibi, and made a series of inventions such as Liu Ma, Kongming Lantern and Zhuge Liancrossbow. Zhuge Liang's great wisdom is deeply rooted in the hearts of the people. Besides, in Jiang Ziya, Jiang Ziya achieved nothing in his early years. Later, he went south to protect the Western Zhou Dynasty and sent troops to crusade against the Shang and Zhou Dynasties. Most of the time, he had a headache. He relied on the help of Master's friends all the way and finally won.
