How to refactor the following codes?

I have the following codes, I think the content is too large and I am deeply think about how to refactor it, may someone has good advice to refactor it ?

List<AccountEntity> fillNameAccounts = agentDao.getAgentListByIds(accountIdList);
    for (T bean : results)
    {
        for (AccountEntity entity : fillNameAccounts)
        {
            String chineseName = entity.getChineseName();
            String firstName = entity.getFirstName();
            String fillName = StringUtils.isBlank(chineseName) ? firstName : chineseName;
            String entityId = entity.getId().toString();
            if (bean instanceof AgentPostResponseBean)
            {
                if (StringUtils.equals(((AgentPostResponseBean) bean).getParentId(), entityId))
                {
                    ((AgentPostResponseBean) bean).setParentName(fillName);
                }
                if (StringUtils.equals(((AgentPostResponseBean) bean).getPosterId(), entityId))
                {
                    ((AgentPostResponseBean) bean).setPosterName(fillName);
                }
            }
            else if (bean instanceof ImportAgentPostResponseBean)
            {

                if (StringUtils.equals(((ImportAgentPostResponseBean) bean).getParentId(), entityId))
                {
                    ((ImportAgentPostResponseBean) bean).setParentName(fillName);
                }
                if (StringUtils.equals(((ImportAgentPostResponseBean) bean).getPosterId(), entityId))
                {
                    ((ImportAgentPostResponseBean) bean).setPosterName(fillName);
                }
            }
        }
    }

Thanks.
