Arrival Ideals: At present, there are many international and domestic flights to Beijing.
Besides, you can take a high speed train to this capital city from Shanghai (5-6 hrs), Xian (5.5 hrs), Guangzhou (8-9.5 hrs), etc.
Two full days and a half day sightseeing covering the grand Tiananmen Square, historical Forbidden City, spectacular Temple of Heaven, man-made wonder Great Wall of China, royal park Summer Palace, traditional Hutong, etc.
Consider, too, the generational issue at play here: The lovely lady you’ve been crushing on’s parents and grandparents are the ones exerting that pressure to get married, even though she herself may not feel that she’s ready or interested.
That's because her grandparents' and possibly (depending on where in China she is from) her parents still value marital stability above all else in their time, given the instability and volatility of their eras.
One friend with an actual boyfriend of 2 months commented that 2 months is long for Beijing.
Even if a guy has a girlfriend or wife, it often doesn’t keep him from going after other women.
Likewise, many women, including many Chinese girls, are not deterred by the guy having a girlfriend (or wife), knowing that the guy likely won’t be either.
