Which attractions in Lanzhou will be open or closed during Chinese New Year?

We will be arriving in Lanzhou on Jan 28th and be there until January 30th. We know this will be the beginning of Chinese New Year. We worry that many things will be closed during this time and transportation might be running on a restricted schedule. Will any of the major attractions be closed? What attractions will be open for us to visit in Lanzhou and how easy will it be for us to get there?
