“主会场”有用main venue表达，venue表示“举办场所”，英文解释为“The venue for an event or activity is the place where it will happen.” 例如：

The International Convention Centre is the venue for a three-day arts festival.

国际会议中心是为期3天的艺术节的举办场所。

“分會場”用的表达为other segments of the show。

在CGTN的报道中“主会场”则用了major venue和main stage两种表达，“多个分会场”：multiple sub-venues.

请查看以下双语例句：
