Which platform is better for Zhihu to travel to Australia?

To travel to Australia, I suggest you go to Qingyi to check the travel guide of Australia or the travel notes of other travelers, and record in detail what you want to play, buy and eat, so as to know what you want, because the Australian travel guide on Qingyi is very deep and personalized. In the second part, you should choose the booking platform. If you join a group, go to Tuniu; if you are free, go to Ctrip.
