Thousand× 4 does not carry, so thousand new = 1 or 2, Happy New Year is a multiple of 4, and new must be an even number, so new =2.

The product of Le× 4, the unit number is 2, so Le =3 or 8. Thousands of New× 4 = Le (carry or not carry), Le =8 or 9. So music can only be 8.

Le =8, which means that year ×4 has no carry, so year = 1.

Le× 4 = 32。 After decimal 3 is added with the unit number of the product of fast× 4, the unit number is year = 1, that is to say, the unit number of the product of fast× 4 is 8, and fast =2 or 7. It is easy to rule out 2, so fast =7.
