If it flowers at that time with yellow flowers then it is likely to be C. tangutica or one of its forms, like C. Bill McKenzie. There are a fair number of named ones. However all of them are pruned the same way. They are in Group 3 for pruning, if you want to check it out. Otherwise start at the base of the stems and look for the first pair of healthy buds and cut off everything above them. Brutal, but it flowers on new wood and you are encouraging it to produce new growth. We do ours starting about now when the buds are easy to see developing.
