On September 16, Apple iPhone7 and iPhone7 Plus were officially launched in mainland China. In order to let NetEase Kaola sell more Apples, NetEase CEO Ding Lei broadcast the waterproof performance of iPhone7 on the NetEase News client and NetEase Kaola overseas shopping live broadcast platform. The live broadcast was viewed by 5 million people.

NetEase Kaola Online Shopping said that on September 12, NetEase Kaola Online Shopping launched iPhone7 pre-sale, and limited sales will be opened in three periods every day. Starting from September 16, users who participated in the reservation have received their mobile phones one after another, and Ding Lei is one of the first early adopters.

During the live broadcast, Ding Lei put the iPhone 7 connected to the Bluetooth speaker into the fish tank while the video was playing. After filling it with water several times, the water surface quickly covered the body. During the live broadcast for more than an hour, the video playback was not affected by the underwater environment. Later, he also tried the iPhone 7's underwater shooting, calling, and power on and off functions, and all operations were successfully completed.

Ding Lei really spared no effort to advertise his products. During the live broadcast, he also downloaded apps such as NetEase News, NetEase Cloud Music, and NetEase Kaola Online Shopping on his mobile phone.
