The fortune teller said that the lock needed to be unlocked.

Haha, you must have been cheated by the landlord. It's been almost ten years since I learned Yi. I really haven't heard of it. There's a yin-yang lock or something. On the other hand, if you really want to have them, they are innate and acquired, so you can't solve them. So don't trust the fortune teller. Don't cheat money, it will damage your morality.
