I think seven plus one is better. My family lives in Shenyang, but I work in Shanghai. I go back to Shenyang twice a year, and every time I go back, I have to go to Seven Plus One for a haircut, because the service there is incomparable to other stores, and even Shanghai rarely has such good service. Last time I went home on May Day, they had a new rule that shampoo should not be less than 30 minutes (I think it was this time). I have been looking for the stylist Zhiyuan there (it seems to be similar to this name, but there is a far word anyway). He is wearing a pair of glasses, and his skill is really good. You can try.
The address of the new store "Qijiayi" is: No.0/89, Zhu Min Road, Heping District, Shenyang (I think the hairdresser here is better than the old one), and the telephone number is: 024-23580260, 23580360.
