The merchants in this place are designed to cut it open, and the reason why they sew it up is because it is convenient for inspection and packaging, and it is also convenient for clothing stores to iron their coats. Because the coat is folded during transportation, it will inevitably produce some creases, so the clothing store should conduct inspection after receiving the goods. If they want to hang them up and put them in the shop, they need to iron them to make their coats smoother. If that line is open, it's actually not convenient to iron.
