Hi Xianbing,
Cute kitty, but it should not be included in your profile photo. The picture in your photo should be a close-up image of your head and shoulders that clearly shows your face--without animals, props or anything other than you. Read through Upwork's best practices for How to Choose A Good Profile Picture.
You can optimize the first part of your overview/summary by removing the following:
":globe_with_meridians: Your Global Procurement and Supply Chain Expert :globe_with_meridians:"
When clients search for freelancers, only the first 200-225 characters of your summary are shown. This means you have very little space (approximately two short sentences) to get their attention. You want clients to see their goals (your services and results) in this small space. You should avoid emojis and marketing/promotional-type statements.
Your portfolio, skills, and employment history look good.
You may want to add one or two Specialized Profiles that focus on specific services or completely unrelated services. Having a specialized profile can help increase a freelancer's searchability.
You should also consider adding a project catalog. The project catalog allows you to setup a pre-packaged service that clients can buy without you sending a proposal. Due to higher than usual requests for project catalogs, reviews and approvals are taking a minimum of 10 business days. Read Get Started With Project Catalog for more information.
Good luck!
