It is reported from rinkside that Yan Han has sustained a minor injury on his right knee, which kept him off the ice for a week. That probably has affected his performance in Nations. Wish him recover soon.
From a 12.28 news report on Chinese Nations, Boyang said he didn't perform up to his training level in the short program, but was satisfied with his free skate. He also said he will work on his skating skill as well as performance execution to prepare for Junior Worlds next March.
Hope both of them can perform to their strengths in the upcoming events!
A few other rinkside reports:
Wang Yi was having a high fever, missing both practice sections, but managed to compete in the evening while taking the entrance examinations for postgraduate students in the daytime:shocked:

Zang Wenbo injured his ankle during the 6 minute warmup for free skate, but tried his best to finish the program, while the crowd encouraged him with applause

It was also said that Zhang He missed Naitons because of sprained ankle...
All I can say is recover soon and best regards for every athlete...
It's written in official announcement that there will be bonus for difficult jumps in Chinese Junior and Senior competitions.
Though the official file for the details about how to give bonus has't been find yet, I have calculated it from lots of protocols:
For men, skaters will get +0.5 points in tes for 3A and +1 points for quad in SP while double of that in FS. For ladies they will get +0.5 for 3-3 combo in SP while +1 for 3-3 and +2 for five different triple jumps. Bonus will be given when these difficult jumps are fully rotated regardless of success landing or correct take off.
There will be a 'B' marked next to TES for bonus in protocols. For example, in this competition, YAN got +1 in SP for 4T and JIN got +1.5 for 3A and quads. They both got +3 in FS for 3A and quads. TENG Zijing(12th in FS) got +1 for his falled but rotated 3A. LI got +2 in FS for five different triples though her 3Lz got an edge call.
Sorry for my poor Engllish……I hope I explained this rule clearly.
Thank you, xiangfuzi

That is better than I could have explained it. I somehow over looked this rule...
Btw. Thanks admin for creating a video thread
