Actually, the reason Xiaoxiao thought there were no locks here is that she didn't see anyone with locks.
The sauerkraut was drugged at the time, and she had thought about buying a lock, but considered it might not be so easy to make. Such technical work like matching a lock with a key was beyond her, and she didn't believe she had that capability.
Later, she set up a workshop and brought in two big dogs to prevent theft.
Thinking about it now, the family would get bigger in the future, and they can't just leave and ask someone to watch the house. It would be more convenient to have a lock. Seeing the blacksmith shop, she thought of coming in to ask, not realizing that this place actually had locks.
But the locks were too expensive. "Uncle, don't worry, we won't make you lose money; I'm just saying you'll earn less profit. No one likes making a losing deal, right? So, how about forty taels, not more?"
