Oh, my god, the pronunciation is tiān, and the glyph is: the word people has a word "mouth" on it. The original meaning of word creation is the boundless sky above people's heads. Initially refers to space, as opposed to the earth, and later extended to the sky and space.
The sky refers to the high altitude above the ground, and refers to the space (sky) outside the living range of human beings (the earth). Space: the sky, the sky, the highest land (the Big Dipper), the deep sky (the metaphor of heaven and abyss is completely different) and the unconstrained style (the metaphor is bold and unconstrained).
During the Spring and Autumn Period and the Warring States Period, ideological progress and humanistic rationality flourished. The concept of "God" has been gradually replaced by the natural "Heaven", which is the embodiment of moral public opinion and forms a foundation of China's cultural belief in later generations. "Sacrificing to Heaven" is the most basic belief element in China culture.
