The double J/\ensuremathψ (DJ) production in direct photon-photon collision is investigated. It is found that the J/\ensuremathψ production rate in this process is of the same order of magnitude as those of previously discussed rates, which hints that the dominant J/\ensuremathψ inclusive production process in the direct photon-photon collision is still not being touched. As the DJ production process has a clear distinction from the single J/\ensuremathψ inclusive processes in the final states, an experimental study of it would be helpful to clarify the validity of the color-singlet model.
