Here's wishing you a belated welcome to Wikipedia, ChunyangD. I see that you've already been around a while and wanted to thank you for your contributions. Though you seem to have been successful in finding your way around, you may benefit from following some of the links below, which help editors get the most out of Wikipedia:
Also, when you post on talk pages you should sign your name using four tildes (~~~~); that should automatically produce your username and the date after your post.
I hope you enjoy editing here and being a Wikipedian! If you have any questions, feel free to leave me a message on my talk page, consult Wikipedia:Questions, or place ((helpme)) on your talk page and ask your question there.

In my opinion, your edits are a significant improvement. But something has gone wrong with the references now numbered 4,5,6,8,9. Maproom (talk) 11:58, 8 November 2018 (UTC)
Hi ChunyangD, I'm working on the following pages: Terry stop, Consent search, Traffic stop, and Warrantless searches. I put some references to case law in the Talk pages and I'm trying to fill out the pages over the next few weeks. Most of the text on the article pages is not mine, so I'm planning to basically write them all. You're welcome to join me, if you have the time! Seahawk01 (talk) 04:30, 9 November 2018 (UTC)
