Why are there more and more transnational marriages now?

Foreign countries are much more open than China, and those foreigners who can go abroad and come to China are relatively better. So, how do many China boys compare with excellent foreigners? They don't know how to take the initiative, put themselves in their shoes and take care of others. Among them, there are some "straight male cancers" and "super male chauvinists". Their sister-in-law will certainly like foreigners who are better than them. In fact, it will also be liked by many women, so China girls don't like foreigners' foreign nationality, and like considerate, caring and sexy men, no matter what nationality.
