The objective of this report is to know the German Negotiation Styles from 7 aspects.
Also the customs and habits are introduced from four aspects, social etiquette, clothes ceremonial, dining etiquette and taboos.
At last, the summery is about a few notes during negociation with German, such as, make an appoitment；get there on time with neat modest clothes；behave decently; take things reasonably; keep silent instead of putting forward opinions without solid basis.
In general, all business activities somewhat formal should make plans. Send invitation letter 1-2 week in advance if you want to invite someone or hold a event. Send a receipt in certain time if you won't come. In that case, no response would be considered rude.
German has a precise structure with many grammar rules. which will reflect itself in expression.
