A long time ago, people in China didn't know English, and people in Britain didn't know Chinese. How do they communicate? How did translation come into being?

What you need, you have a reason to live. When translation is needed, translation appears. Before the birth of translation, either human beings didn't understand language and only made gestures; Either the language has just been born and the traffic is still underdeveloped. All tribes call themselves Yelang, and they don't communicate with the outside world and don't need translation.

If you are talking about the transitional stage of translation, people communicate mainly through facial expressions, body language and the tone of speaking their own language. Some experts have shown that when people communicate, the meaning conveyed by pure language only accounts for 20% of all information, and the rest mainly depends on the speaker's tone, expression and body language. The meaning of the same sentence expressed in different tones can be completely different. Is this easy to understand?
