China's solution to political instablity regarding succession is resolved by Deng Xiao Ping by establishing a system from which the current generation leaderships will pick the third generation leadship after they retire. It offers the below benefits:
1) Because the current generation leadership has the power to pick the third generation leadership, it gurantees their political survival and thus allow them less worried about their future after they leave the command posts. This will eliminate their strong desire to turn dictatorship.
2) Because the third generation is being selected and arranged during the reign of the first generation leadership. The future leaders will have more time to get trained and establish their reputation.
3) When the second generation leadership is in power, the first generation can offer substantial guidance and influence over the new commanders. And their advices will be heeded because the old guards have the ears and hearts of the third generation.
4) By the time the third generation gets into power, most elders in the first generation are gone by natural cause, and thus there won't be substantial conflict among the first and second generation fighting over the consulting position to the third generation leadership.
