There is a math problem to be solved. I love you, China × I = 1999. I love you, too, China. What numbers do they represent?
I ≠ 1, otherwise I × me, plus the subsequent carry, will have no carry.

Country × I =? Country, country × (I-1)=? 0, China and I-1 must be 5 and even numbers. When China =5, I-1 is even and I am odd. When China is an even number, I-1=5 and I =6.

Me × me+? = country 1, when country =5, I = 7,7 love you, 5× 7 = 519995,519995 ÷ 7 =74285, I love you, China = 74285,

When I =6, the country is 4,6 loves you 4× 6 = 419994,419994 ÷ 6 = 69999,

So we don't need different numbers, there are two, we need different numbers, only 74285,
