The oldest is Yanshan Hotel Dry Cleaner, which is located at the west end of No.4 Road, other No.4 Road and Dieyang Road. There is also a gatehouse near Yanhe Road Post Office east of the south end of Xiye Street. I remember a large area and White Tiger Mountain. I can't remember the specific name.
It's hard to say which is better now that it's all privately owned.
