OC中get、set方法，我用set方法把名字设成中文，却总是显示不了，这个是什么原因？？
#import <Foundation/Foundation.h>

@interface Person :NSObject{
char* _name;
int _age;
}
//名字
-(void)setName:(char*)name;
-(char*)getName;
//年龄
-(void)setAge:(int)age;
-(int)getAge;

@end
@implementation Person
//名字
-(void)setName:(char*)name{
_name =name;
}
-(char*)getName{
NSLog(@"姓名：%s",self->_name);
return _name;
}
//年龄
-(void)setAge:(int)age{
_age=age;
}
-(int)getAge{
NSLog(@"年龄：%d",self->_age);
return _age;
}

@end
int main(int argc, const char * argv[]) {
Person* p1=[Person new];
[p1 setName:"八神"];
[p1 getName];
[p1 setAge:10];
[p1 getAge];
return 0;
}
这个是什么原因？？求指教
