During the complicated development of the Covid-19 epidemic, we cannot study and work as usual. Therefore, online learning is an effective solution being used by many schools and workplaces. However, everything has its advantages and disadvantages! First I want to talk about the pros first because everyone wants to hear the good things first, right? Online learning helps us absorb knowledge quickly and effectively, can review if we do not understand and add what is missing for us to improve ourselves. Next is the disadvantage, because it is not possible to interact and contact directly with the teacher, so learning is quite difficult, some families may not have conditions, the internet is stable, so it will have trouble connecting to the teacher. Some students may bring unhealthy content to the classroom or use it to play video games or watch youtube. I hope in the future the covid-19 pandemic will end and we will have healthier online lessons, without any disadvantages.

hello yuto
how are you? Have you received the item I sent you? I'm looking forward to hanging out with you after this summer break! I have too many assignments and things to do so I can't email you often. I have some places you might like when we hang out. The first is the terraced fields-Hoang Su Phi, At Hoang Su Phi the terraced fields go up to the clouds, the scattered golden fields are the small roofs of ethnic people hidden in the groves. Every afternoon when sunset falls, the color of clouds in the sky mixed with kitchen smoke emanating from the stilt roof makes the scenery at this Ha Giang tourist destination full of peace, rustic but indescribably majestic. The second is Ma Pi Leng Pass, Ma Pi Leng Pass is located on the Happy road connecting Dong Van and Meo Vac. This is known as the most beautiful road in the rocky plateau. If you come to Ha Giang and try once to be able to drive a car precariously between the sky-high rocky mountains on one side, the deep abyss on the other side, and watch the Nho Que river winding like a strip will make you experience many wonderful experiences. wonderful range of emotions. It is like a big challenge for adventure lovers. The third is Dong Van Stone Plateau, a place that is no longer strange to all Vietnamese people. If you come to Ha Giang without visiting this world-famous geopark, it is a waste. Dong Van stone plateau is also home to a majestic and unique natural scene and preserves the very unique culture of the H'Mong, Lo Lo, Pu Peo, and Dao ethnic groups. Next is the Flagpole Lung Cu is at an altitude of 2000 m above sea level, the only place where Lo Lo people live. Standing on the Lung Cu flagpole, watching the national flag fluttering in the wind, seeing firsthand the first point where the brush stroke was drawn to make the S-shaped map is when national pride and love for the country overflowed. . Lung Cu flagpole is a tourist destination in Ha Giang that is loved by young people. There are many more unique places that I haven't mentioned yet such as Quan Ba ​​Twin Mountain, Noong Lake, Dong Van Old Town,... Maybe I should stop writing here, I miss you so much, I'll probably go next time. It will be fun to play next! Goodbye!
