In the cross-border e-commerce arena of big health, high-quality customer service is the cornerstone of building trust, yet it also presents numerous challenges.

The barriers to product expertise are high; sales consulting requires not only precision but also in-depth communication, while traditional customer service training has a long cycle and poor effectiveness. Under globalization, time differences and language barriers become the 'invisible killers' of immediate service response, where any delay can erode customer trust. More critically, how can the high advertising traffic effectively be converted into private domain users who can be reached long-term? How can pre-sales consultation and post-sales care seamlessly connect, ultimately driving repurchases?

This has become the growth code that every big health brand must crack as they go global.
