As the analysis shown in the last answer, the Verbal-object word帮(bāng)忙(máng) can not add object again, instead, it is used in the structure of ‘帮(bāng)+O+忙(máng)’ such as bang- tāde-máng 帮他的忙 ‘do somebody a favor’.
However, there are some verbal-object words can also add object directly, includes chūtái 出台 ‘introduce’, diǎnzàn 点赞 ‘like’.
