[Wo Long] Five Things You Must Do In Stage One (Tutorial Stage)

There are a few things us soldiers and warriors might miss in Stage One of Wo Long: Fallen Dynasty... Things that could really help us learn how to fight well, or make our adventure easier. Let us help our fellows avoid making the same mistakes.
If you are new to the world of Wo Long, and want to know where to start and what to do, then this guide is for you.
Update: Regarding the third tip (obtaining the Baihu armor set), I have heard that not every warrior is blessed with the privilege of obtaining and equipping it. While not quite as strong as the Baihu armor set, an alternative would be finding and equipping the Lieutenant General armor piece. Said armor piece may be found in a treasure chest inside the building just beyond the Changgui, and can be accessed by going around the right to reach the other side of the building, jumping onto the ledge, then falling into the hole on the building's roof. Once you have accessed the building's interior, the treasure chest is quite difficult to miss. Killing the Changgui to access this area is optional, although you might have to escape from it when you exit the building, if you happen to startle it.
