Can the plaintiff's lawyer contact the defendant directly?

You can contact the defendant directly. The plaintiff's lawyer's duty is to safeguard his own legitimate rights and interests, and he can contact the defendant in some cases. For example, before the trial, the plaintiff's lawyer can communicate with the defendant on mediation issues, but generally will not express any views on facts and evidence issues, so as not to affect the case. In addition, all actions should be for the legitimate interests of the parties. Therefore, the plaintiff's lawyer can contact the defendant directly, but in general, the lawyer can't express any views on the facts and evidence.
