definitely would not be regretting it. There are plenty of reasons for it, but let’s focus on the main of them (http://www.lot.com/airline-tickets/flights-to-china). Firstly, there are plenty of marvelous festivals in China. Chinese people love festivals and every single of them is attended by big crowds of people. Secondly, Chinese history is one of the most interesting history in the world. Because of the fact that China has over 4000 years of the history, you can be sure it would be very interesting and fascinating journey!
Other two cities, which everybody should visit is London and Moscow. As a result of the fact that both cities are placed in Europe, they can be visited during one trip (because there are many flights from London to Moscow). London is a city like none other in the entire world. There are the most famous sights and museums (http://lot.com/airline-tickets/cheap-flights-from-london-to-moscow). Furthermore, it is one of the most multicultural city! When it comes to Moscow, it is a city that never sleeps. There is an amazing night life, with plenty of famous clubs and pubs.
