Giải hộ bác hhhhh votttte Trong cuộc đời đầy truân chuyên của mình, chủ tịch Hồ Chí Minh đã tiếp xúc với văn hóa nhiều nước, nhiều vùng trên thế giới, cả phương Đông và phương Tây. Trên những con tàu vượt trùng dương, Người đã ghé lại nhiều hải cảng, đã thăm các nước châu Phi, châu Á, châu Mĩ. Người đã từng sống dài ngày ở Pháp, ở Anh. Người nói và viết thạo nhiều thứ tiếng ngoại quốc: Pháp, Anh, Hoa, Nga… và Người đã làm nhiều nghề. Có thể nói ít có vị lãnh tụ nào lại am hiểu nhiều về các dân tộc và nhân dân thế giới, văn hóa thế giới sâu sắc như Chủ tịch Hồ Chí Minh. Đến đâu Người cũng học hỏi, tìm hiểu văn hóa, nghệ thuật đến một mức khá uyên thâm. Người cũng chịu ảnh hưởng của tất cả các nền văn hóa, đã tiếp thu mọi cái đẹp và cái hay đồng thời với việc phê phán những tiêu cực của chủ nghĩa tư bản. Nhưng điều kì lạ là tất cả những ảnh hưởng quốc tế đó đã nhào nặn với cái gốc văn hóa dân tộc không gì lay chuyển được ở Người, để trở thành một nhân cách rất Việt Nam, một lối sống rất bình dị, rất Việt Nam, rất phương Đông, nhưng cũng đồng thời rất mới, rất hiện đại.”
