Mình không có ai bài này 

Đây là dạng nâng cao mà

xin lỗi mk hk biết.Nhưng chắc hk phải tất cả mọi người đều như mk đâu,có lẽ họ biết nhưng họ hk muốn nói hoặc ngại viết thôi.Mk rất hiểu bây giờ bạn đang như thế nào,mk cũng đã từng thức trưa để học nhưng đến khi mk hỏi thì những bạn online đều hk trả lời.

thôi tặng bạn để an ủi nhé!!!

Nothing shows you love your country more than showing it through clothing or accessories! Each country has their own identifying image that defines who they are, and how they are perceived internationally. In Viet Nam, it's Ao dai.You can purchase flags, bumper stickers, or any other emblems at a local store. Hang them on your car, your front lawn, or anywhere that can outwardly show you respect your country. Remember to treat the flag with the utmost respect. Many countries have parades displaying the pride they have for their country, or country of origin. It could be on the day of independence, or some other historic date, but the important part is to celebrate with your countrymen. What happened in your country on this day in history? Did they win a war? Did they gain independence? Recognize that holidays are much more than just occasions for parties or, in some countries, sales at department stores. Acknowledge the solemnity inherent to certain holidays, especially those that commemorate a victory that involved bloodshed.
