I don't know if I will exist .

Life and death are just different forms of life in different periods, just like the Yin and Yang of Tai Chi. There is Yang in Yin and Yin in Yang. Life and death never stop

I take the previous life and the next life for granted. We can call it "reincarnation". I might suffer what I've made and done but as long as I do my best, my effort and will take over the unknown-new me.
