Some General Comments and Observations from our Trip

The quality of the hotels was very high, all being clean and with good facilities. At every hotel except Beijing we had double beds, even though we were warned in advance that this was unlikely. All had bar fridges, and most a lockable safe.
Staff in hotels and restaurants, and the people in general, were friendly and helpful. We felt welcome everywhere we went.
Many places had imported wines which were very expensive. Local wine (in particular the Great Wall label) was acceptable and cheap. Local beer was very good.
The food was of an excellent standard, although a roast dinner and a steak on our return were more eagerly anticipated as the time for our return drew nearer.
In Shanghai, I could not find the list of restaurants I had been given as recommendations before we left home. So using the brochure from Travel Indochina and our own sleuthing, we ate at Heaven on Earth (very good), 1931 Cafe and Bar (poor), Merrylin (close to our hotel, a wonderful find, cheap, mostly Chinese diners, excellent food with English translations and pictures, and local inexpensive wine), and M on the Bund (Western food, too much meat and few vegetables, expensive, but great views)
Planning of the Infrastructure which will be required in future is well under way, with projects being undertaken well in advance of the need. Money for these projects is no problem, nor is permission required or politics involved which differs vastly from any major development project in Australia.
Our 4 guides varied in skill and personality, although the last two were excellent. Their spoken English was first class, all majoring at the tertiary level in English.
Seeing what is happening in China makes me wonder whether we all should be learning Mandarin. Perhaps the US, Europe and Australia will be the third world countries in future with heavy debt to China which will hold the world's wealth!
Where was our favourite place/area? Hard to say, but the one place to which we would return immediately is Yangshuo.
Witnessing the one-child policy in action, and in particular the Children's Palace, one can't help but wonder what society will be like in 30 or 40 years' time. With all those spoilt children (we saw them everywhere, and it was fairly obvious), what will the leaders/businessmen/executives be like then? The Chinese natural politeness and desire to "save face" may not remain in future as the youngsters become (perhaps) the selfish and self-interested middle aged. Time will tell.
In summary - a great trip, Travel Indochina designed an excellent range of activities for the itinerary, and our travels were trouble-free. Fifteen days was about the right time for the locations which were included - any less would mean the inability to include Guilin and Yangshou which were our favourite scenery.
