我要你的建议 中国一带一路政策对中亚带来什么影响吊我的胃口，我在找关于这个政策的中文书籍呢。你有建议的？

Вопрос "Делегации Южной и Северной Корей проводят переговоры за закрытыми дверями" Когда читал новости, у меня возник вопрос. Что такое "за закрытыми дверями"? Наверняка это то же самое с "не публиковано"? Я бы рад, если можете перевести "за закрытыми дверями" на английский.

中文的语法 ”平时十分拥挤的汽车，今天人倒不多。“ I think "倒" here acts as a verb, but I noticed that right after this word comes an adjective "不多"。I wonder it is possible...as far as I know, if we wanna add an adjective after a verb for describing the extent, we‘ve got to add "得" like “倒得不多”。I hope somebody could explain it to me. Thank you.

关于中文的语法 ”有人说如果掌握一点儿日语的语法，那么要看懂日文报纸，就不是太难的事了。“ 我不了解 ”那么“ 在这里有什么意思。也许 "then"? 我猜出”如果“ 和 ”那么“ 呼应。 对吗？ 谢谢您帮助我理解。

中文的语法 “当我们一打开日文报纸，就会发现日语里有许多用汉字的词语。” [当] - 我查着词典发现了”当“ 有 ”时候“的意思。这是对吗？ 我的回答对的话，在”当“和"时候”中有什么区别？ 谢谢。

关于中文语法 "他们一边看地图，一边望着站牌对照。" The sentence I wrote above is the one from the text I'm now reading. I wonder why it's possible to put 对照 at the end of the sentence. Is it also correct to put it before the object , for it's a verb, like "一边望着对照站牌"? Thank you.

On a deeper level I got stuck while I'm reading this text written below. --------------------------------------------------------------- He recounted how it is strange when he draws alone, because he was not out there in the streets playing basketball with others. But on a deeper level, Del Carmen tapped into the experience of moving his own children to a new city due to his work, just like Riley’ Dad. He moved with his family from Los Angeles to Emeryville, and told how it is a very difficult transition for the kids. ---------------------------------------------------------------- Here's what I cannot see: "but on a deeper level". I guess it means: "as he goes on talking..". I would like someone to help me out with this so I can make sure my translation is correct or not. Thank you on beforehand.
