Acceptable itinereary to get visa for mainland China via Macau departing from Bangkok

I plan on booking a return flight from Bangkok toin Macau. Then would travel by train from Zhuhai to Guayangzhou and stay 3 nights in Guangzhou, then return by train to Zhuhai. From Zhuhai would transit to Macau to take flight back to Bangkok. My question is would China Embassy in Bangkok issue one based on this itinerary? If so can I purchase a return train ticket from you between Zhuhai and Guangzhou and can you email me the ticket so I can present this to the Chinese Embasssy? My departure would be Apr 24th and return would be Apr 27th. Please advise.
