Ying and her husband were very welcoming and friendly. They communicated with me only in Mandarin though, so it was easy for them to speak to me as they don't speak English much I think. There wasn't a fan in my room when I first arrived and as it was summer and really warm, I mentioned this to them. When I came back to the apartment in the evening there was a fan in my room - they had gone out to buy one! Thank you so much Ying. 谢谢！
