Is Trip.com reliable?

I’m from Canada and I’ve been intending on booking things through Trip.com, but my travel advisor said to stick to Booking.com and Expedia because Trip.com has a lot of fraud?

I wanted to book the Rezen Murray Hotel in Shanghai and Qinfu Hotel in Beijing. But even if we were to use the other 2 sites, neither hotels are on them.

I’ve already put so much time into picking the perfect hotels on trip.com I would hate having to redo all that on different sites
