Answer:
North
Step-by-step explanation:
Of course, if we could look at a map, it would be easy to figure it out.
Let's suppose we don't have access to a map but we have the GPS location information for both cities.
Shanghai is located roughly at 36° latitude North, 114° longitude West.
The capital of China is Peking (Beijing), it's located roughly at: 40° Latitude North and 116° Longitude West.
So, we first notice that Peking is North of Shanghai (40° vs 36°).
We also see that the capital is a bit more to the West than Shanghai (116° vers 114°).
So, you'll be going North... a bit towards West.
On most compass roses, that would count as simply North. since the deviation from the exact North is minimal.
