According to the tradition of our people from ancient times, on the 23rd of the lunar calendar on the 23rd day of the lunar calendar, Mr. Tao went to heaven to report everything in the house of the owner to the Jade Emperor. Therefore, in these days, families in Vietnam will clean the kitchen, buy goldfish to worship and see Mr. Cong and Mr. Tao back to heaven.(không bị phá bỏ)

Thông thường, thời gian khai bút thường vào ngày đầu tiên của năm, có thể ngay sau giao thừa. Tuy nhiên, hiện nay, không nhất thiết là phải khai bút đúng ngày đầu tiên, cũng không cần quan trọng ngày tốt hay xấu.

Normally, the opening time is usually on the first day of the year, right after the new year. However, at present, it is not necessary to have to write on the first day, it does not need to be important on good or bad days.

Chỉ cần từ ngày mùng 1 đến trước khi đi học trở lại, các bạn có thể lựa chọn giờ hoàng đạo trong ngày để làm lễ khai bút. (Nếu không biết đâu là giờ hoàng đạo thì hãy hỏi ý kiến của ông bà hoặc cha mẹ).

Only from the 1st day before going back to school, can you choose the zodiac time of the day to make the opening ceremony. (If you do not know what is the zodiac time, then consult your grandparents or parents).

Học sinh thường có suy nghĩ rằng, nếu đầu năm khai bút chữ đẹp thì cả năm việc học sẽ gặp thuận lợi, nếu chữ xấu, cẩu thả thì cũng sẽ ảnh hưởng đến chất lượng học tập. Vì thế, trước khi khai bút, các bạn hãy xác định trước xem mình nên viết những gì, dài hay ngắn…

Students often think that if the year of the year of writing is beautiful, the whole year of study will be convenient, if the word is bad, negligence will also affect the quality of learning. So, before you start your writing, determine in advance what you should write, long or short …(đang dần bị biến mất)

nhầm môn

Đề kiểm tra 15ph mà thế này à? Không giống trường mình =))

An: Hello Manh , What are you doing ?

Manh : Oh , Hi An . I'm reading a magazine about tsunami .

An : What is tsunami ?

Manh : Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. The speed of tsunami waves depends on ocean depth rather than the distance from the source of the wave. Tsunami waves may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters. While tsunamis are often referred to as tidal waves, this name is discouraged by oceanographers because tides have little to do with these giant waves.

An : It sounds terrible .What is it cause ?

Manh: First , it causes many deaths . Since 1850 alone, tsunamis have been responsible for the loss of more than 430,000 lives. Second , the amount of energy and water contained in a huge tsunami can cause extreme destruction when it strikes land. And finally Tsunamis not only destroy human life, but have a devastating effect on insects, animals, plants, and natural resources. A tsunami changes the landscape. It uproots trees and plants and destroys animal habitats such as nesting sites for birds. Land animals are killed by drowning and sea animals are killed by pollution if dangerous chemicals are washed away into the sea, thus poisoning the marine life.

An : How can we to stop it ?

Manh : From my point of view, we need many factors to simulate Tsunami wave than we can find solution for this problem. One of this factor as Gobo A.E. mentioned above, also we need to know how many cycle per each period for example 10 years that happened and also the height of the wave when it attach the land. When we study deeply all factors then we can find solution such as we can made some gates in front of the coast lying horizontal in water when the level of water increase more then the normal this gate change its position to the vertical to crash the wave height and to reduce the damage on the land behind it.

An : That's true.
