This is a cup
If you want to combine billboards 2 and 3
you must buy another one
Synthesize it and install it
I found that the original billboard 1 was back in the bag
And you will never use it again
You can put the two ads at your leisure Swap the cards
But the number of patient pick-ups is still up to six times (based on billboard 3)
That is to say, you use billboard 1 to pick up 4 times ***320 people , if you change it to 3, you can only order twice more
If you order 3 six times, you can’t order 1 again
