    Based on previous studies deriving the chiral Lagrangian for pseudo scalar mesons from the first principle of QCD in the path integral formalism, we derive the electroweak chiral Lagrangian and dynamically compute all its coefficients from the one family technicolor model. The numerical results of the p4p^4 order coefficients obtained in this paper are proportional to the technicolor number NTCN_{\rm TC} and the technifermion number NTFN_{\rm TF}, which agrees with the arguments in previous works, and which confirms the reliability of this dynamical computation.Comment: 6 page
