As the chief engineer said " We have to invent every single technical break thru by ourselves. We can't depend on other" Indeed as china was denied access to space technology It also talk about Kuaizhou rocket and network of micro satellite
On under sea exploration It talk about the Jiaolong undersea submersible deep dive in Mariana trench and building a better deep sea submersible.

Up above, thousands of satellites are constantly in orbit. While most are substantial spacecraft weighing thousands of kilograms, some members of this extraterrestrial community are much, much smaller - the microsatellites. And if Wang Yang and his team have anything to do with it, they’re set to get even smaller. That’s because he’s developing a satellite that weighs just 100kg - the first of a projected constellation of microsatellites capable of creating a space network for the whole planet!
