In the following formula, the same Chinese characters represent the same number, and different Chinese characters represent different numbers. Please change the Chinese characters in the formula into appropriate numbers to make the formula tenable

Year × year = (year × 11) × (year × 11) = 121 × year × year = flower similarity, that is, flower similarity = 121 × year × year; flower similarity is a three digit number, 121 times 1-9 to exclude; because year and year can not be equal to 1, so 1, 2, 3, 5, 7, can be excluded, they can only be decomposed into 1 times themselves; because



In the following two formulas, the same Chinese character represents the same number, and different Chinese characters represent different numbers
Known:
Ba mountain night rain = night mountain
Ba + mountain night rain = mountain night rain
Ask: Bashan night rain?
If the names are the same, it's purely intentional


A:
From the second formula: Ba + Yu = 5, then the mountain = 1, and the mountain is at the end, so when the mountain = 1, Ba = 7, then the rain = 3 does not meet 7 + 3



In the following formula, the same Chinese characters represent the same number, and different Khan characters represent different numbers?
Young people set up their ambition early
+Young people set up their ambition early
————————
If you want to be young


Young people's early ambition + young people's early ambition = young people with ambition is equivalent to vertical: young people's early ambition × 2 -------- young people with ambition, so "less" is an even number less than 5, which may be 2 or 4
