No , "held out" is correct. It means "to delay taking some action as long as possible ." "The man was on a flight from Viet Nam to the US. He was a heavy smoker and he not had a cigarette all day. He held out as long as he could but finally couldn't stand it anymore and went to the bathroom, lit a cigarette and took a few puffs and quickly put out the cigarette. "

Not 100 percent sure but I think she means " cute little girl" , "little girl" . A cupcake is a small, cute little cake and it sounds like an older experienced women giving advice to a younger girlfriend. It is just a term of freindship I think but this is not a common way to refer to someone. I think the women just made that up herself but we know what she means.

I think they are all OK although my feeling is that right side version is slightly better.

it's correct but I would probably use "importance" instead of "significance" . we need more context to say whether or not "significance" should be used.

HI EDUARDO , GREAT JOB . I JUST CLEANED IT UP A LITTLE What I've learned about China after a business academic trip Some weeks ago, I returned from a 10 day trip to China, organized very well by FIA Business School. It was a business academic trip, part of my Masters course I just took this year. It included visits to some companies and classes in Chinese universities. I had very good expectations before I [WENT], based on opinions from my friends that [HAD] already been there, but it [ REALLY SURPASSED ALL MY EXPECTATIONS (i think this is what you mean but sure)]and that is what I want to share with you together with some lessons I've learned from them. Thanks one more time to FIA Business School, Toschio, Harold by organizing this trip and giving us this opportunity to know [SUCH AN ] amazing country, learning from Chinese people and the colleagues I met on this trip, [WHO ALL CONTRIBUTED TO THIS PLEASANT 10 DAY TRIP.] There is a Brazilian advertisement that says "nobody returns from a trip the same way THEY went". In other words, it means that a trip changes the way you see and think about the world. For me, it is one of the main truths that exists and with MY China TRIP was NO different for me. I also believe that the best way to know a country, its people, culture, economics and politics is going there, not only reading news, books and opinions from other people, that is important but not enough. It is the same AS "Gemba", the Japanese expression IN WHICH we apply in Continuous improvement projects to say "go there and understand" and take off your own conclusions. Before I begin, I would like to say that IN NO WAY DO I PRETEND TO BE ABLE TO EXPLAIN what happens in the whole China. I visited only 4 cities (Shanghai, Ghangzhou, Dongguan and Beijing) and all of them big cities. So, I describe below ONLY my perception about what I saw in these cities, what I heard from the company’s executives we met and from the classes we had at universities there.

Undermine means to try to ruin or block someone's success . 1.The Democrats are always trying to undermine President Trump's plan for a border Wall. The wall still isn't built after two years. 2. Drinking heavily and taking drugs could undermine your chances of a good future career. 3. Hitler's plan for a invasion and takeover in Stalingrad during WW2 was undermined by a terrible snowstorm that winter that made condition for attack impossible.
