# 28 - The Three Tiers of Culturalization with Chui Chui Tan of Beyō Global
This is the third episode in our three part series on cross-cultural research. In this episode, Erin and JH chat with Chui Chui Tan, author of International User Research and Founder of Beyō Global. Chui Chui walked us through her "three tiers of culturalization", which can help international and cross-cultural researchers focus in on what they need to be researching. She also talked about how to prioritize different elements of your research based on the culture you're researching, the product you're working on, and how those two things interact with each other.
