There is a panda next to the Weibo nickname, which represents the Panda Guardian activity. It is an activity on Weibo calling on everyone to protect giant pandas. You may have clicked to participate in this event, so there is this pattern next to your nickname. It’s similar to Arbor Day, Youth Day and so on. And this pattern means that you are one of the guardian pandas. :

"Panda Guardian" is a new attempt to upgrade Weibo's charity from "donation-based charity" to "product-based charity". Experts in Weibo-related fields said that they will increase product design and investment, significantly lower the threshold for public welfare, increase users' interest in public welfare projects, and make it easy for everyone to participate in public welfare projects.

Volunteers who participated in the spring planting said that through this participatory experience, they had enhanced their awareness of the protection of biological diversity. They all said that the charity trip is for you and me. With the participation and contribution of everyone in the public, a social trend of natural ecological protection will surely form, our living environment will become better, and the living home of mankind will be more beautiful! The China Greening Foundation will, as always, join hands with Sina Weibo and all sectors of society to contribute to nature protection public welfare undertakings.
