The core of culture is value,any value can’t be separated from the specific cultural environment. We must depend on the traditional culture of the ethnic minority to cultivate the core value of socialism. Traditional culture of ethnic minorities is an important part of Chinese traditional culture, many contents of minority traditional culture, such as patriotism,honesty,unity cooperation,diligence,dedication and the pursuit of harmony and happiness are consistent with the core values of the socialism. Taking family as the base point and taking the traditional festival as the carrier to cultivate the core value of socialism are the effective way to cultivate the core value of socialism in the reality.
