Many recent works on the methodology of intercultural philosophy point to a fundamental dilemma of the discipline: if there is a common ground for intercultural understanding, then the essence of this ground is universal instead of multi-cultural; if there are irreducible and incommunicable factors in different cultures, then complete understanding seems to be impossible. In this paper, I propose that this dilemma is founded on the assumption that intercultural philosophy is equivalent to intercultural understanding. I argue that, however, intercultural philosophy should begin with questioning. Instead of understanding another culture using one's own conceptual scheme, intercultural questioning puts one's conceptual scheme and traditional worldview into question. The new questions obtained by phenomenologically reducing traditional thought will become a ground for intercultural dialogue without reducing one's culture to another culture. Finally, I will use a case in Chinese philosophy to demonstrate the process of intercultural questioning.
