This article has more details on everyone.
Li Zijun is in fine form at this stage and says to have started preparation much earlier this season after experiencing the swap-out fiasco last year. The short is coming along well but the free still has issues. She trains with Li Xiangning and Zhao Ziquan now, and they help push each other.
Jin Boyang has been consistent with his big tricks and received loud cheers from the crowd. He hints at doing some unexpected tricks.
Yan Han has returned to systemic training for 1.5 months after being off for 3 or more months due to surgery. He says he is about 50% of where he needs to be and needs to focus on domestic competitions in September. His shoulder injury is not completely healed. He can't spin and do quads here yet but 3axels are fine. Timing is tight and he will treat his domestic competition in September as practice for China GP. He currently trains with Zhao Hongbo.
Yu / Zhang fell on their throw. They said there are plenty of difficulty choreography and new elements, each with transitions preceding. They have only had these programs for more than a month. Lori is here to address issues identified at these test skates.

This article includes some tidbits from Lori.
For pairs programs, she only choreographed for the three Chinese pairs this season.
She feels Sui / Han needs to focus on skating and not on the pressure of being WCs, but concludes that they will be fine since they work very hard and have a special aura as a pair.
She says Peng is talented artistically and can be a choreographer some day. Jin / Peng is a new pair but don't skate like one.
