This sentence is complex because it contains a main clause "Nol Bu went home to his successful rice crop" and a subordinate clause "but he could not enjoy it." The subordinate clause cannot stand alone as a complete sentence and depends on the main clause for context and meaning.
u rong it is compound.
I apologize for the confusion. You are correct. The sentence is compound because it contains two independent clauses that are joined by the coordinating conjunction "but." Thank you for pointing that out.
