Bilingual Services

In Sanya, mostly Mandarin is spoken in hotels, restaurants and other public places. We recommend that you download a translation app for your phone such as Google translate, which will greatly facilitate communication. JW Marriott has an international English-speaking management team who have been fantastic to work with and will be available to resolve any issues and answer questions. While many hotel staff members do not speak English, we are making arrangements for volunteers from the local University English graduate program who speak both English and Mandarin to assist our participants with airport transfers, conference activities, and VIP guest services.

IMMS and IDSSE will also provide professional translation during the general sessions, thus enabling more Chinese participants to understand the presentations given in English, Chinese presentations to be translated into English, or for other language speakers to answer questions raised by Chinese participants.
