This HEP program in Hong Kong started in 2015. The objective of this program is to bring theorists, experimentalists and accelerator physicists together, and to facilitate stimulating discussion among participants. Issues on the physics, detectors and colliders with an emphasis on the future of high energy physics will be addressed. Discussion sessions regarding topical interests, such as gravitational waves, unexpected progress at LHC made before the program, as well as their implications for future research may be organized. As part of the program, a four-day conference will be held during 22-25 January 2018. We also hope to release some white papers for the particle physics community documenting the physics goals, options of future colliders, and the reach of the related experiments.
