所以，要留意自己的起居环境，让它像五星级饭店一样乾净。

So be mindful of your own environment. Make it as clean as a first class hotel.

肿瘤会破坏正常解剖关系，要始终留意移位的结构。说错“它在这儿”一百次也比说对“它曾经在这儿”一次要好。

A tumor destroys the normal anatomy. Always be on the lookout for displaced structures. It is better to say "there it is" and be wrong a hundred times than to say "there it was" and be right once.
