In the future, we should put emphasis on pushing the dual core structure of Zheng ( Kaifeng) -Luo, coordinating the polarization and equilibrium relationship, realizing the stability and uniform of the brand, extending the industrial chain, building the smart tourism network service platform in the development of Zhongyuan Tourism Circle.
