There is no word in Chinese for "Easter"--not originally, at least. Being of a different tradition and different belief, the idea of Christ and Easter was not a part of that Eastern world. And so, when Christians came and began to teach of Christ and of His mercy and His power and His love, they needed to choose a word to describe the Western springtime celebration of His life. The way they choose to remember this day was simply "復活節", or "Resurrection Day".
"There is a resurrection, therefore the grave hath no victory, and the sting of death is swallowed up in Christ."
"And this is the gospel, the glad tidings...That he came into the world, even Jesus, to be crucified for the world and to bear the sins of the world, and to sanctify the world, and to cleanse it from all unrighteousness; That through him all might be saved whom the Father had put into his power and made by him; Who glorifies the Father, and saves all the works of his hands."
Happy Resurrection Day!
