Flew back in First on the 168 yesterday with family. We were directed to the (adequate, but very busy) China Eastern Lounge 77. Reasonable selection of food, but wouldn't aim to spend more than an hour in there if you want something to eat or drink prior to the flight. No sign of a passenger escort being offered to us or any of the other F pax, but it didn't take more than 10 mins to get through immigration and security in any case.
