Asking for the feng shui meaning of the idiom (seven up and eight down) and the attributes of the five elements. Can it be hung on the wall as calligraphy?

Seven up and eight down means being undecided and melancholy. There are also fifteen buckets to fetch water. This idiom comes from the Book of Changes. The 64 hexagrams are divided into eight palaces. Each palace Among the eight trigrams, the seventh hexagram is the wandering soul hexagram, and the third hexagram is the returning soul hexagram, so it is not suitable to be hung on the wall as calligraphy. The seventh one is the Gen hexagram, which is the mountain, and the eighth one is the Kun hexagram, which is the earth. Hope it will be adopted.
