Hello, I'm Quenhitran. An edit you recently made to Passive solar building design seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. — ALittle Que nhi  ( talk to me ) 03:59, 10 February 2017 (UTC)
