Let`s talk about the meaning of BTA One day,when I am wandering on Quora,I find an entertaining phenomenon.The meaning of BTA is different to Chinese and Westerners.For us,in china,when it comes to BTA, it refers to three big internet enterprise,respectively, Baidu,Tencent,Alibaba,just like Google,Facebook,Amazon in US. Until one day,some one on Quora answers a question about"Why certain Professor leave Calth for ETH zurich?",he refers it to BTA--been to America,beause the Professor is Germany and he had achieved BTA in a sense. What an Interesting culture gap! Would you tell me what you get at the first glimpse of BTA?Whether you are from US,Europe,China or any other regions.
