富饶
1 “回合内不可花费超过你原来拥有的金币数量”是补充说明的，联系上下文，这里“原来拥有的”就包括了在一次行动中选择拿的2元钱。
You get back all the gold you spend to build district cards, but not the gold you spend for other reasons (paying the Tax Collector, for example).You cannot spend more gold than you have during your turn.
2 不算一次“建造”行为
If you build it into your city, it does not count as your one district this turn
3 这个诶有找到具体说明，规则和FAQ似乎都没提到，我个人认为应该也是要花费4+牌数的
