Are the four people from Harbin going to Beijing with a group or to save money by themselves?

1, it's cheaper to go by yourself, but it's more troublesome, booking hotels, buying tickets and so on.

2. The time to play by yourself is your own, and the collective time is others';

You can walk as you like, or you can change your itinerary or add items at any time.

4, go by yourself, eat by yourself, buy whatever you want, eat whatever you want, listen to others, eat what, when and how much? Wait, this is not for you to decide.

5. All the scenic spots can be played as long as you want, and it is very unpleasant to travel with a group.
