exhibit, state, relate, explain
陳 centers on laying something out so it can be seen or understood: exhibiting objects, stating facts, relating a story, or explaining an idea.
陳 combines ⻖ (mound, hill) with 東, which likely contributes the sound. The original meaning may relate to arranging or displaying things in rows, perhaps like goods laid out on a hill or platform.
Picture a mound ⻖ where someone has laid out items from the east 東 for everyone to see: an exhibit that states and explains their story.
For チン, imagine a chin-high exhibit on the mound: chin -> チン, and you have to state what each item is.
