常見錯誤

❌The street is two-way direction.
✅The street is bidirectional.
💡'bidirectional' already contains the idea of direction; adding 'direction' is redundant.
❌They have a bidirectional relation with each other.
✅They have a bidirectional relationship with each other.
💡The noun form 'relationship' is more natural than 'relation' for this meaning.
