lead the White House?

I don't know exactly how you might put it. The White House is a house, in the sense that the President and his family live there. It is also an office building, in the sense that his staff have offices there, as well as some of the government agencies. "Lead" would not really be accurate, because the White House is a home and an office building--there is nothing there for the President to lead. Certainly he "leads" his staff, but that is true whether they have offices there or not. (There is a building next to the White House called the Eisenhower Executive Office Building where many of the President's staff have offices.)

Enter would be a better option, but perhaps you could say either that he would occupy the White House, or take up residence there. The fact that it is both a residence and an office building rather complicates your translation.

Thank you. In Chinese there is one word to describe both meanings. It's always difficult to find the proper word when I do my translation.

Yes, i'll bet it's not easy at all. I find that your English is quite good, and wish you every success in your endeavors.

how about simply "enter the White House and lead the country".

Thank you!

Thanks! I have so much to learn. ^_^
