The lotus also appears in Vietnamese fashion. The harmonious combination of “Yem” and lotus flowers has greatly contributed to the timeless charm of Vietnam through our long history. “Yem” refers to an ancient Vietnamese bodice used primarily as an undergarment that was once worn by Vietnamese women of all classes.

ying on the east bank of the Red River, about 13 kilometers from Hanoi, Bat Trang isL a small village established between the 14th and 15th centuries. This peaceful place is famous for its ceramics and pottery products. Thanks to its long–lasting history and development, the village’s works have been accumulated over the years with many special designs that have been exported all over the world.
Highlight of the trip David Pires Tavares Martins, from Portugal team, may be one of the delegates who has the most unforgettable memory of Bat Trang. Even though his broken leg was a great challenge to his mobility, David’s enthusiasm for activities, such as shaping and coloring pottery, was never in doubt. Having had a good first impression of his ingenuity, the pottery shop owner generously gave David a ceramic product as a souvenir, together with a nice wish: “Hope that you will be a successful chemist and achieve the Nobel Prize in Chemistry in the near future.” The shop owner’s goodwill message is typical of the friendliness and hospitality that Vietnamese people so often display to foreigners throughout the world. The Temple of Literature
he Temple’s grounds are home of two distinctT but related institutions: the shrine to Confucius named Van Mieu, and the former university for mandarins called Quoc Tu Giam, literally the “Temple of the King Who Distinguished Literature”. The former was first built in 1070, and the latter was established in 1076. In early days, Van Mieu was opened only for nobles, royalty and other members of the elite. Six years later, Quoc Tu Giam was eligible to educate the growing civil service, becoming Vietnamese first university. In 1484, the King Lê Thánh Tông erected 116 steles of carved blue stone turtles with elaborate motifs to honor talent and encourage study. The complex of doctors’ steles are a valuable historical resource for the study of culture, education and sculpture in Vietnam. Until now, there are 82 steles remaining. They depict the names and birth places of 1307 graduates from 82 triennial royal exams. Nowadays, Vietnamese students often go there to express their gratitude to ancestors and pray for better achievements in study, making the place very crowded before examinations. IChO students also visit the Temple for both sightseeing and wishing luck in following exams. Today

Unlike normal days, it was hard to see any relaxed faces; instead, the students seemed a little bit worried and some of them even skipped breakfast. Despite that, 75 teams still arrived at Hanoi University of Education to take part in the exam, full of excitement. The test started at 9 am and lasted for 5 hours in a very formal atmosphere. At 2 pm, all teams were picked up by their guides and returned to La Thanh Hotel for a well-earned rest. In general, all the students considered that the exam questions were not too challenging hard. According to Thomas Vialon (France), the exam questions were not so difficult but they were pretty long. Although the test only lasted five hours it covered all the general knowledge of Chemistry. He said “The practical test was quite well-organized with modern equipment On the day of July 23rd, at 6:30 pm, and laboratories.

ietnamese cuisine is all about balance. It is reflected in the way that Bundit Diloknawarit ingredientsV are selected. This balance, they believe, is not only pleasing to the Thailand taste buds but beneficial for the body as well. It is the precarious balancing act Look at my face! It’s the result of an of the five basic taste sensations - salty, sweet, bitter, sour and spicy - that give experiment!!! Vietnamese food its depth and intrigue. Salt – Sodium chloride (NaCl), common salt, is a useful raw material. Several useful substances can be obtained from it, including chlorine, hydrogen and sodium hydroxide. Salt is widely used in the food industry as a preservative and flavor enhancer. In Vietnamese cuisine, fish sauce (“nước mắm” in Vietnamese) is a special condiment emblematic of the salty taste. The unique characteristic of fish sauce is its salty flavor and fishy smell. An interesting characteristic of fish sauce is that once mixed with other ingredients it loses its fishy odour. Sweet – Sucrose (C12H22O11) is sugar. The organic compound commonly known as table sugar, cane sugar, Masada Koichiro beet sugar or, usually, just sugar. Saccharose is an obsolete Japan name for sugars in general, especially sucrose. It is best “I live near Hokkaido prefecture” – known for its role in food. Sugar plays an essential role in “Hajime mashite!” means “Nice to every typical dish in Southern Vietnam cuisine: sweet gruels meet you!” and “Watashi wa…” (Che), sweet and sour fish broth (Canh chua) , steamed means “My name is…”!!! sticky rice (Xoi), grilled meat rolls (Nem nuong) and dishes with coconut as an ingredient. Spicy – Capsaicin (C18H27NO3) is an active component of chili peppers. Because of the burning sensation caused by capsaicin when it comes in contact with mucous membranes, it is commonly used in food products to give them added spice or “heat”.
