码住 is a casual public “saving this” under a useful post—the comment-section version of making a note for your future self.
A private bookmark disappears into a folder. 码住 leaves the bookmark where everyone can see it. Under a checklist, recipe, or guide, the comment means “saving this—I’ll want it later,” while quietly telling the creator that the post was worth keeping.
That tiny gap between intention and follow-through is part of its charm. People 码住 workout plans they may never open again, but the default meaning is still sincere: this looks useful enough for my future self.

搬家交接清单发群里了，最后一项：水电表一定要拍照。
Bānjiā jiāojiē qīngdān fā qún lǐ le, zuìhòu yí xiàng: shuǐdiànbiǎo yídìng yào pāizhào.
“I posted the moving handover checklist in the group. Last item: always photograph the utility meters.”

码住。上次退房，我就因为少了这张照片说不清。
Mǎ zhù. Shàng cì tuìfáng, wǒ jiù yīnwèi shǎo le zhè zhāng zhàopiàn shuō bu qīng.
“Saving this. Last time I moved out, I couldn’t prove anything because I didn’t have that photo.”

这次先拍，再交钥匙。
Zhè cì xiān pāi, zài jiāo yàoshi.
“This time, take the photo before handing over the keys.”
Ren says 码住 after one overlooked item—a photo of the utility meters—reminds him exactly how he lost money last time. The comment saves a practical lesson, not just an attractive post.
