SHENZHEN — YouTube sensation IShowSpeed (38 million subscribers), known in China as “Hyperthyroid Brother,” brought his signature chaotic energy to Shenzhen yesterday with a livestream featuring a dramatic test drive of BYD’s amphibious Yangwang U8 SUV followed by a tech shopping spree at Huawei’s flagship store.
The 22-year-old internet personality, fresh from his Hong Kong visit, began his stream at a water testing site for the ¥1.09 million ($150,000) luxury off-roader. Footage shows the normally boisterous creator turning uncharacteristically nervous as the vehicle entered the water.
“OH MY GOD! Are we sinking? We’re sinking! I’m scared!”

His assistant advised against seatbelt use “for easier escape,” while the Chinese driver calmly assured safety. The subsequent beach driving attempt ended with the vehicle stuck in soft sand, adding to the comedic spectacle.



At MixC Shenzhen’s Huawei store, the influencer enthusiastically purchased the cutting-edge Mate XT foldable phone (¥19,999/$2,750), calling it “the most insane tech I’ve ever seen.” His antics drew massive crowds, with footage showing him climbing out of the BYD’s sunroof—prompting police intervention.
