Getting a visa for mainland China

Hi, I'm currently in Hanoi, Vietnam and I tried to apply for an L to visit China as a Tourist. My application was rejected because my hotel bookings didn't match my schedule (I had read online that a number of people were approved with only the first hotel booked, but I was not). They now refuse to accept any subsequent applications.

Would I still be able to enter if I applied for it in Macau, I've heard this process is simpler.
