How to join topic with hashtag"#"?

Using hashtags are a great way for users to find your item faster. For example, #fancyfriday, #mypet, #BIG2017, #spring2017, #free shipping, etc.

A hashtag can convert items with the same hashtag into clickable links. This helps people find a series items they are interested in. Your listings with hashtag# can be viewed when people click a hashtag and view the hashtag item list. You can also click in your hashtag# to see what items others are uploading.  

Add “#xxx” to join the special topic, let more people see your items and get more offers.

For example:

• Publish an item with description "#fancyfriday", then you'll automatically join the campaign prepared for each Friday with lots of fancy items!
• Publish an item with description "#mypet", then you'll automatically join the campaign prepared for showing your story and happiness with your pet to other 5milers!
• Publish an item with description “IKEA brown fabric sofa #big2017”. When you click the #big2017, you'll see the listings that contain this #tag.
