Traveling to China with a side trip to Thailand

We are Canadians traveling to China for 6 weeks to visit our son who works there and our daughter in law who is Chinese. In the past we had an 8 year tourist visa with multiple entries. We are applying for a new 10 year visa with multiple entries. We plan to travel to Thailand for a 12 day holiday with our son and daughter in law during our holiday in China, returning to China before coming home. Is there any issue with doing this? We don't want to book our Thailand trip until we are sure. We are considering two visa options a ten year short term family visa with multiple entries or a tourist visa with multiple entries. Your thoughts? I am wondering if the tourist visa gives more options for travel in China.
