[Before the formal trade, four different expressions will appear on the screen. Exclude the expression 'most want to trade' and the expression 'least want to trade,' then choose one from the remaining two expressions.]
[This stage will involve lie detection; one must not make insincere choices.]
[The system will automatically exclude the expression 'least want to trade,' and match a trading object from the remaining three expressions for you.]
[Both parties will conduct multiple trades; the specific trading process is as follows:]
[1. In each trade, both parties must provide at least '2000 gold sand' and '2000 minutes of visa time' as trading items.]
[On this basis, the trade ratio will be dynamically adjusted according to the specific number gap between the 'Gold Sand Provider' and the 'Visa Time Provider' within the trading area.]
[2. Both parties can choose 'trade' or 'rob.']
[If both parties choose 'trade,' the trade is completed, and the trading items are exchanged.]
