Taiwan had created a few of their own events in hot topics than copying everything from China. If you are talking about in-game events like rescue jin, then there has been no difference between any servers. What Jiburiru was trying to say is certain aspects of the game can be different such as plot instance reward for getting all 3*, prices on ninjas/items, buffs/nerfs on mains and ninjas (still debatable if they are the same in all servers or not).

But the issue is that they haven't specifically said which aspects of the game would be different (they won't outright and say it). In-game events like GNW, sage, etc. aren't different. What we can compare what is different in other servers so far is the prices on the ninjas/items and random prizes. For example, our server didn't get killer bee in chapter 10 of the plot and it costs 50 coupons to get a lucky board dice in germany.
