Yes, please help the new comers. The new comers learnt too much forms but not enought partners training.
I think the old guys may do some ga sam sing(格三星), chi sau, cho sau, pad hitting, wrestling, light sparring.... with them.
Anyway, we also need to give time for them to train alone, may be 30 minutes. For Chinese Kung Fu, it is necessary for learners to know how to train alone.
Sometime, even they just take a rest and have a look of the others. It is benefit to them. It can be considered as part of the training.
