求翻译：但如果一旦进入到了日方现场能不能顺利地与客户沟通交流呢？像这些问题如果不去亲身体验，无论怎样的专注和揣测都是不能从根本上解决的，对人的职业发展来说也是重大的限制。当时我这样认为着。是什么意思？

But if once you have access to the Japanese side can successfully communicate with the customer? As these issues without first-hand experience, no matter how dedicated and speculation is not fundamentally resolve, is also significant restrictions on people's professional development. I think so.
