It's pretty hard to say if 30k is good or not since we know very little about China. Remember when there was a lot of buzz of the Xbox One charting very high in Amazon Japan when preorders began? (Example: http://www.dualshockers.com/2014/06/21/xbox-one-manages-to-top-amazon-japan-best-seller-chart-on-its-pre-order-debut/ ) When it finally launched in Japan, we saw many major retailers being nearly empty.
Also, according to the Games in Asia poll, 6x as many Chinese gamers preferred the PS4 (http://www.cinemablend.com/games/Chinese-Gaming-Poll-Shows-PS4-With-57-Vote-Xbox-One-With-11-66406.html ). The sample is actually pretty decent at 6665 people, especially when most online polls tend to have less than 1000 sample sizes. Also, this poll was running for weeks, so the X1 had plenty of time to catch up, but it never did.
