Daily quests give you two of each Lv.5 Manyu's.

You can farm 1-3 to spawn a 12 stamina Secret Garden. This is probably your best source for manyu's until way later when you start farming 12-3.

Edit: By the way, try not to start a new thread for every question. Use the general thread, I'm sure people'll help you out there!
