Are you sure you don't mean shao erkuai? Chao erkuai is a stir fried dish served by any restaurant making Yunnan cuisine.
For shao er kuai it's most frequently sold from little carts on the street, mainly in the morning. There are also some shops specializing in it. There is one on dongfeng xi lu, near the intersection with yieryi dajie, just uphill from the mouth of fengzhu jie.
Older people may be a challenge. They often either don't speak Putonghua or mix some Yunnan Hua in even when they think they're speaking Putonghua. But most understand Putonghua even if they can't speak it well.
All urban and most countryside young people speak pretty intelligible Putonghua.
Never done this route, but guess it would probably be nice: hire a car to take you down close to the southern tip of dianchi. S103/S214 to Fuxian Lake. Skirt down to southern tip of Lake and head toward Tonghai on back roads. Break east before reaching Tonghai and pass through Huaning. East on S304/S305 and then north on S206 to Luoping.
I did my residence permit last year. Went through my state's central government (the office responsible for statewide criminal record information, forget the exact name). Was able to use this in Kunming directly without further authentication, though I did pay extra to have the report notarized.
If you have the appropriate budget and want a unique experience, this is definitely the best hotel choice in Kunming. It has a few drawbacks like the inability to drive a car straight up the entrance. As a boutique property, it also naturally lacks some of the amenities of a big hotel. But this is more than made up for by the location, thoughtful design and personal service.
I am not an employee of the mask. Numerous other users on, and the administrators of, GoKunming know that is the case.
I just think the Mask is a nice place with nice staff and owners and reasonably priced drinks. But I'm not such a big EDM fan so I tend to go only for live music or when a group of friends is headed there.
I also think it's a very safe place for people who don't invite trouble upon themselves—certainly safer than many of the surrounding establishments.
I would suggest that the most recent one star review should be removed as it contains zero review content, and is rather just a response to other reviewers.
