tip:Do not keep a spare key over the door or under the door mat.

小贴士：不要在门上或者门垫下面留备用钥匙。

Never leave a spare key in a hiding place like under a door-mat, in a flower pot or inside the letter box--a thief will look there first.

不要把你的备用钥匙藏在你认为安全的地方，比如门垫下面，花盆里或信箱中，那些都是小偷首先会搜查的地方。

For the door is open and the welcome mat is out.

星门已经敞开热烈的欢迎你们！
