Why did Qi rise rapidly after the demise of the Western Zhou Dynasty and what did it do?

At the end of the Western Zhou Dynasty, Zhou Youwang was killed by Quan Rong. After Zhou Pingwang ascended the throne, he moved eastward to Luoyi, which began in the Spring and Autumn Period of the Eastern Zhou Dynasty. In this process, the main rulers of many countries participated, but Qi did not appear in the changes of the country. So what is Qi doing?

In fact, at the time of the demise of the Western Zhou Dynasty, the monarch of the State of Qi was Qi Zhuang Gong Lv Gou. He has been in office for 64 years. Although he didn't show up, he actually achieved a lot. Because he succeeded to the throne as a king, when Lugou succeeded to the throne, it was the time when the Zhou royal family was fighting everywhere, and then it gradually failed. Later, Zhou Jun was almost completely annihilated, and I was almost captured. All these have exposed the weakness of the ruling power of the Western Zhou Dynasty. At this time, emerging vassals, such as Qin Jin, with the support of the government, began to show their military strength and helped the Zhou royal family conquer for many years. However, Qi has been watching the fire from the other side, quietly conditioning and developing its strength.

Later, it was obviously a correct decision for Qi Zhuanggong to choose to develop the economy and implement the government of Taigong. In this way, Qi gradually prospered and its overall strength grew rapidly. However, the dispute over the Central Plains kept Zhou royal family and vassal states busy, and no one noticed the silent development of Qi State.

Later, Qi led an alliance to help vassal States solve problems, and was finally recognized as one of the overlords in the Spring and Autumn Period by other countries. On the basis of Qi Zhuanggong's economy, the growing Qi State further expanded its territory and eventually became a real big country. I think that during his reign, Qi Zhuanggong experienced the demise of the Western Zhou Dynasty and the establishment of the Eastern Zhou Dynasty, but he did not participate in it, but has been quietly developing his country's economy. This made full preparations for the later development of Qi.
