First part: Air Astana. Skip if you don't fly with this company. Air Astana broke all plans with the breakdown of its board, the flight was delayed, then they sat on the plane for a long time, then turned back to Almaty on an hour-long flight.
From Almaty, a direct flight to Hong Kong is visa-free for citizens of the Republic of Kazakhstan for 14 days. A visa to visit Hainan must be done before departure. We were in Hong Kong for 3 days and as always one day was not enough.
