小组讨论与阶段性汇报
group discussion and cross pitches
6月30日-7月4日是同学们开展小组讨论，明确思路和打磨方案的重要时间段。在这几天中，同学们不但要在小组协作时克服时差等线上交流带来的障碍，还要在7月1日和7月3日两天完成两次阶段性汇报。在各小组的头脑风暴中，起初模糊的想法逐渐成型，并在两次阶段性汇报中得到了导师们的指点，逐渐完善成具体可行的方案。
the period from 30 june to 4 july was an important time for the students to work in groups, clarify their ideas and polish their proposals. during these days, students not only had to overcome barriers including time difference in online communication when working in groups, but also had to complete two cross-pitches on 1 july and 3 july. during the brainstorming sessions, the initial vague ideas were gradually shaped and refined into concrete and feasible solutions with suggestions from the teachers during the two cross-pitches.

学员感想：
reflections of participants:
choi pak yin：the most exciting part of the tsinghua gss is the sdg hackathon. my teammates come from a very culturally diversified background, while some of them believe in the power of social innovation and some of them believe that the government should take the lead in environmental protection. with all these great ideas coming together, we have figured out a solution that would enhance the engagement of various stakeholders. thank you, tsinghua, for hosting this amazing event!
jorge enrique ascencio damian: through this hackathon, i learned a lot of things, especially about the sdgs, and why they are important for our society and future. in the hackathon i also got the opportunities to work with other international students and propose a sustainable solution towards an environmental problem that is affecting our world. i’m looking forward to applying all the knowledge i got to the benefits of our society. thank you!
