How do I travel from Aruba to Liuzhou without having to fly via Amsterdam?

From Aruba to Liuzhou, there are no direct flights. And you need to reach Beijing or Shanghai first and then take a flight to Liuzhou. If not willing to transfer at Amsterdam, you could take the flight to Shanghai first by transferring at O'Hare International Airport in Chicago. Since you two have not married yet, visa is required. About the details, you could consult the USA Embassy in China.
