I will be in Singapore on 10 May and returning back to Melbourne on 30 May.

During that time, I intend to take a trip to Shantou and Guangzhou for sightseeing for about 10 days all up. I would like to apply for a China visa before I leave Australia. However, on section 2.3 of the China Visa Application, it says: "Planned date to enter China in the next 3 months". At this stage, I do not know the EXACT that I will be entering China because I am going to shop for the best travel deals when I get to Singapore and it would also depend on flight availability, etc.

So what shall I do? Can I put an approximate date of entry and return? thank you
