InOverseasWork, anddomesticTeam communication is almost inseparable from DingTalk. But problems arise as soon as a video conference starts—you sit down and open DingTalk, the connection seems normal, but after a few sentences, the video starts to freeze. The other person's mouth is moving, but the sound is completely out of sync. You have to ask "Can you hear me?" three times before you get a response. After a minute of smooth video, it becomes a blurry mosaic again. Screen sharing is even worse; you flip to the third slide of the PPT, but the other person is still stuck on the cover.

It's not just meetings; even everyday file transfers via DingTalk are a nightmare. A colleague stationed abroad needs to send scanned copies of a contract back to China, and DingTalk freezes halfway through the transfer; resending it still freezes. Using DingTalk...documentIn online collaboration, it takes three seconds for the cursor to respond when you drag it, making it impossible to align in real time when editing a plan with colleagues in China.
The same applies to Yuque Docs and WPS Cloud Docs; any domestic online collaboration tool is slow to access from overseas.
Why does my internet speed lag when using domestic software even though it's not slow?
Because you are overseas, while DingTalk's servers are in China, there are public network lines thousands of kilometers in between. This line has not been optimized at all, and data packets have to go through multiple international nodes, resulting in latency of more than 200ms and a high packet loss rate. Video conferencing and real-time collaboration have particularly high requirements for network quality, so lag is inevitable.

Later, I used QuickFox, a VPN for accessing Chinese websites, and the problem was basically solved. It has dedicated lines optimized for domestic office platforms like DingTalk and DingTalk Docs. After connecting, video conferencing latency decreased significantly, screen sharing no longer lagged, and file transfer speeds returned to normal. Contracts and proposals could be sent without waiting. With over 1000 nodes globally, it automatically matches the optimal line whether you're in Japan, Singapore, or Europe, offering 24/7 unlimited speed and data, so even meetings that last all day won't experience speed drops.
