Translating it as president can easily lead people to mistakenly believe that all national affairs are decided by the president, as if he is the sole authority. In fact, a more accurate translation of PRESIDENT in Chinese is "executive officer".
The United States is a country with a separation of powers. The functions of the U.S. president, apart from representing the country in diplomatic situations and serving as commander-in-chief during wartime, are roughly equivalent to the director of the General Office of the Central Government in China, and in many cases, his authority is even smaller.
To obtain funds, one must look at the budget and also require parliamentary approval. The president has no local personnel authority. The personal financial strength of a presidential candidate plays a minimal role; in the United States, one can run for president regardless of family poverty, as there is a comprehensive system in place to ensure that elections are fair and just. It is difficult to influence election outcomes with money. Neither Clinton nor Obama were wealthy.
