People are curious. A few people are. They will be driven to find things out, even trivial things. They will put things together, knowing all along that they may be mistaken. You see them going around with notebooks, scraping the dirt off gravestones, reading microfilm, just in the hope of seeing this trickle in time, making a connection, rescuing one thing from the rubbish.

为你，千千万万遍。

Quality is not a coincidence; it is a consequence.

我们开采的每一吨煤炭都承载着同等重量的责任。
