Translate the following paragraph from English into Chinese.Core Internet technologies are our greatest weakness, and the fact we rely on others for core technologies is our biggest threat. It matters little how large an Internet company is or how much that company is worth if it relies heavily on foreign countries for core components and its supply chains are controlled by others. It is like building a house on someone else’s foundation. It might be big and impressive, but it could be torn down at any time. If we are to seize the initiative in the development of the Internet, and guarantee our cyber security and national security, it is imperative that we overcome the hurdle posed by core technologies and try to perform an “overtake on the bend” in certain fields and areas.
