Hi, guys,
Our Wikipedian friends from China Mainland just confirmed that users from most provinces of China could visit zh.wp directly. Originally they could only visit by "climbing the wall". Most of us guess the lift of the ban is brought by the Olympic Game which is going to be held next week. Though the lift might end after the Game finishes, I still want to share this news with you.
Yeah, they block and then they unblock, back and forth, many times. This is life.
Best wishes, Titan
