As we all know, Xpeng Motors and Ranger publicly used Tesla's "open source patent", while LeTV, Weilai Automobile and Zhiche Youxing borrowed from Tesla's "open source patent" technology.
Unlike Tesla, which can only be upgraded by software, Xpeng Motors can also upgrade car hardware.
For a more vulgar example, all parts of Tesla are nailed with nails, while some parts of Xpeng Motors can be easily disassembled and replaced, which is somewhat similar to that of carpenters in ancient China, who used modular splicing technology instead of nails.
