Underpinned by the rising application of social media to tourism and hospitality, this chapter discussed how various platforms influence tourists' destination selection in China by exploring different types of tourism information and Chinese social media platforms, thus analysing their application and influence on destination selection across the three-stage travel process. This chapter found that tourists' destination selection needs different tourism information produced by individual tourists, destination marketing organisations, and tourism businesses. Thus, Chinese social media platforms have been designed with different functions to apply to tourists' destination choices across three stages of travel. During this process, information characteristics (e.g., positive and negative comments, information variation, richness, and credibility) on these platforms generate positive and negative influences on tourists' destination selection. Based on these, the authors developed a framework for social media for destination selection that suggests several theoretical and managerial implications.

3-D numerical simulation was carried out for flood discharge and energy dissipation process of conical X-shaped flaring gate piers in a hydropower project by using coupled Level Set and VOF method and RNG k-ε turbulent model. The change laws of flow pattern, water surface profile, velocities and pressures distributions in lock chamber of conical X-shaped flaring gate piers were gained. The results of numerical simulation were compared with the model test data and good agreement was found. The numerical results show that, there are differences on both of water surface profiles in lock chamber. With the increase of discharge, water surface profiles falls at the longitudinal axis and vertical diffusion of ski-jump flows are large on the downstream of flaring gate piers.
