To facilitate co-streaming between the two locations, quite a bit of preparation was necessary.
Gaoligong Mountain in Yunnan is deep inland, while Linhai is by the sea, the distance between them being a whopping 3000 kilometers.
Initially, they had expected a high latency, but since the zoo in Linhai had a 5G network, signal transmission was indeed much faster.
However, most places in the mountains had no signal at all!
Sometimes, they needed to climb to relatively high mountain peaks or stay near a village to get a signal.
That is, if they were not using iPhones.
Li Xing and Fang Ye complained that iPhones were the most despised by researchers at the scientific station and the locals; Android phones could still surf the internet and scroll through TikTok on mountain tops, while iPhones had no signal at all, nothing more than a brick.
