China Visa Entry and Exit Time

Hi,

Due to the nature of my job, there are cases where I need to come into China, meet up with a client and leave on the same day and sometimes I need to stay a couple of weeks to complete a job.

Right now I hold a double entry visa that allows me to stay in the country for up to 60 days max each time. If I leave China on Monday on the 60th day of my first trip, can I come back in on Tuesday and start the next 60 days stay?

Or is there a minimum 24 hours where I need to be out of the country before I can come in again?

Thank you so much!
