must-see/must-visit tourist destinations, a must tourist destination ???
The Palace Museum and the Great Wall, the two world-famous scenic spots, are know to all a must tourist destination for people visiting Beijing.
Is 'a must tourist destination' used above OK? If it is correct, say from grammar, does 'a must' sound too enforcing? Are the expressions like must-see and must-visit better?
I read the sentence from a textbook written by old Chinese scholars. No offense, but frankly I don't believe them, so I'd like opinions from native speakers.
Thank you!
