Hello @traciyork . Apologies to everyone and Ms. @trangbaby, in my article I referenced some brochures about tourist attractions, I took the source of the information in those papers and did not leave the source of the information.
I feel that my work was not correct and lack of honesty. I would love to be corrected in future posts. If I write about a place later, if I use some information, I will cite the source directly in my article. Once again, apologies to everyone.
