Today's hexagram:Mountain Wind Gu（䷑）

The Book of ChangesThethirty-eightThe hexagram states that the upper part is separated by fire and the lower part is mixed by water. The fire and water are opposite to each other, and we seek common ground in front of each other.

Hexagram revelation: This hexagram depicts the dialectical principle that although things are opposed, they can seek similarities, and although they are apart, they can complement each other. It symbolizes that in life, differences and oppositions are the norm, and seeking common ground and differences is the ultimate wisdom. The way of observing is preciousSame but Different "- does not require all things to be the same, but to find a way to coexist in differences. Like fire and marsh, they each hold their own position, use their own strengths, do not harm each other, but rather complement each other. When facing differences, there is no need to force consensus, but one should learn to seek common ground while reserving differences; When encountering opposition, there is no need to be either black or white, but one should know how to put oneself in others' shoes.

Xin Song hates not being a thousand feet tall, and the evil bamboo should be chopped down by ten thousand poles.
