Take for example Buddhism, which has had perhaps the deepest impact in China. It is true that Buddhism argues that life begins at conception, when sperm meets egg, and that this life already has a "consciousness." Since it is a life form with feeling, naturally it would be wrong to terminate its existence.
以影響中國民間較深的佛教為例，佛教認為當精、卵結合，生命已經形成，有「識」的存在，即是個有情的形式，當然不該終止其生命。
