左右操作，只有一個黑旗是原創作品的。 For left and right operations, only one black flag is an original work.
二創定義: 又稱再創作、衍生創作或二創，產生的作品稱為二次創作物（或再創作物、衍生創作物）。由於其並非版權法上的常用概念，其實質涵蓋範圍難以確定。二次創作並不是把別人的作品剽竊過來，當成是自己的；相反，二次創作是明顯地以某作品／項目／角色為基調來改編、仿作或加以發展，它的引用及改變意味是很明顯的。 Second creation definition: Also called re-creation, derivative creation or second creation, the resulting work is called secondary creation (or re-creation, derivative creation). Since it is not a common concept in copyright law, its substantive coverage is difficult to determine. The second creation is not to plagiarize someone else's work, but as one's own; on the contrary, the second creation is obviously adapted, imitated, or developed based on a certain work/project/role. Its quotation and change mean obviously.
