Hi @wangting I'd suggest emailing email@example.com to check out that rule, since your two screenshots don't agree.
If you want to express the logic (A OR B) AND C, then the way to do it in a single rule is (A AND C) OR (B AND C) as I've illustrated.
If you find that the rule is getting overly complex, then you can split out the logic into multiple enrichments. I've given a simple example above. In AudienceStream, each enrichment for a single attribute is run in turn for each event, top to bottom, as long as the rule for each enrichment is true on that event. You can use this to achieve most logic that you need.
