Pay one real person who happens to be nearby to walk over and answer a question about right now, on the spot. A few yuan, a few hours. Good for: is this shop open right now, does this charger work, how busy is that street today, is the item still on the shelf — things you cannot search for, that only someone standing there this minute knows. Cheaper and faster than verify_place, but one person and no report. 让一个正好在附近的真人去看一眼，回答一个当下、现场的问题，几块钱、几小时内。适合：这家店现在开着吗、这个充电桩能不能用、这条街今天什么样、货架上还有没有货——这类你搜不到、只有此刻站在那儿的人才知道的事。 跟 verify_place 的区别：这个是一个人、便宜、快，给的是一句现场描述；verify_place 是三个互不相识的人、几十块、出一份可以拿去给别人看的核实报告，适合"这家供应商到底存不存在"这种要留证据的场合。拿不准就用这个，便宜。下单会从账户余额扣款。
