Hello people! I'm planning a trip to China for practice and broadening your horizons. Some moments confuse me. I ask anyone who knows to answer: - Is it true that few people understand English in China? - Is it true that cash is practically not used and you will have difficulties with pay services by cash? - Is it true that it is hard for a foreigner to exchange cash dollars for CNY? - Is it true that exchanging crypto for CNY can lead to jail time? - Is it true that foreigners cannot pay with AliPay and WeChat in China?
