If the denomination of Hong Kong dollars is 1000, then 300,000 is not much.

There are all kinds of birds in the forest. This guy directly withdrew 300,000 cash after the transaction, and walked around in a plastic bag. Did he think the money was too much or his life was too long? The police chased the thief like playing hide-and-seek.
Suggestions: After the transaction, transfer the money online honestly, or deposit it directly in the bank after the transaction, don't make things more dramatic for yourself!
