I believe that in this matter you have to choose and fix your heart on what it is you really believe on. If Jesus is your Lord, then you will not accept that you belong to a symbol of a serpent or even what it represents. If Jesus is your Lord, then you belong to God, your Heavenly Father, and nothing man made, like those Chinese signs, can label you as anyone other than a child of God. You are under God's authority, not the authority of the Chinese dragon/serpent.
