The sum of the two cranes is equal to 8 or 9, and 9 is an odd number, which is impossible. So it can only be 8, so Hang =4.
4+ state+state = 18 or 19, that is to say, the sum of the two states is equal to 14 or 15, and the same 15 is odd, so it can only be 14, so state =7.
7+ city+city = 19, obviously city =6.
So the answer is
Hangzhou -4
State-7
City -6
Love-1
