Head Chair

Rachel Chi
Hello delegates!
I’m Rachel Chi, a junior at Dulwich College Beijing, and I am honored to serve as your president for the Security Council. I first started MUN in 2022, with this iteration of TIANMUN marking my 16th total conference and 10th as a student officer. Over the years, MUN has become a defining part of my high school experience, and I hope this conference proves just as meaningful for each of you.
Every time I write a chair introduction, I wonder what novel advice I can offer to encourage delegates to raise their placards more. But in the end, it can only be this: if you do not speak, you will never be heard. And what is politics but a game of convoluted voice projection? To the new delegates, I hope you take a chance with this conference and step outside of your comfort zone. Don’t hesitate to reach out if there are any concerns, and together, I’m sure we’ll make this conference a great one.
I look forward to meeting you all!
Deputy Chair

Emily Ho
Greetings!
My name is Emily Ho and I am a senior from Grace International. It is my utmost pleasure to serve as a deputy chair for the Security Council at TIANMUN XIII.
MUN has been a formative part of my high school experience. Through it, I have sharpened my skills in articulation, negotiation, analysis, and social aptitude. I’ve learned how to focus under pressure, think on my feet (literally), accept my mistakes with humility, and extend grace and compassion to others.
Delegates, please approach this conference with a refusal to remain stagnant and an eagerness to learn from this experience regardless of whether this is your first or tenth conference. Prepare comprehensively, participate passionately, and have fun! As your chair I will support you along this journey to the best of my ability.
See you soon!
Deputy Chair

Yujian Zeng
Hello delegates!
My name is Yujian Zeng, you can call me Steven, your student officer for TIANMUN XIII. Outside MUN, you might find me dissecting /math/physics questions, analyzing models, or scribbling potential ways to solve a physics question in the margins of my notebook. My MUN journey started with trembling hands at the podium, but I soon discovered that every speech, even imperfect ones, can shape a room’s energy and atmosphere. My favorite MUN moment was when we laughed together after a midnight discussion while eating a “waimai buffet”, realizing diplomacy is about people, not just procedures. My advice is that I would ask you to be bold enough to speak up, listen deeply to others, and not fear challenges; they’re your best teachers. I’m excited to witness your creativity and courage as we debate and solve global crises together at TIANMUN XIII. Let’s make this conference one to remember!
