Great Ancient & Grand Modern Engineering - China has Both! More About Science, Engineering & Technology in China!


Chinese people have built tens of thousands bridges over past thousands of years. The bridges have become an important symbol of Chinese ancient civilization, and demonstrate the intelligence and talent of ancient Chinese people. The oldest bridge still in existence and standing strong in china is the Anji Bridge constructed during the years between 595 and 605.

Ancient Chinese bridges are universally acknowledged and have enjoyed high prestige in the bridge history of both the East and the West. Throughout history, the Chinese nation has erected thousands of ingeniously designed and magnificent bridges. Crossing over mountains, spanning rivers, they have facilitated transportation, beautified landscapes and have become one of the marks of ancient Chinese civilization.

In modern times in particular during the infrastructure boom of the past two decades, bridge-building has proceeded at a rapid pace on a vast scale. Prior to the completion of the Wuhan Yangtze River Bridge in 1957, there were no bridges across the Yangtze River, China's longest, from Yibin to Shanghai, and all overland roads and railways crossing this 2,884 km (1,792 mi.) stretch of the river had to be ferried. There were only seven such bridges in 1992, but that number reached 73 by the end of 2012, including eight new openings in that year alone. In fact out of the top 35 longest bridges in the world China have built 17 of them.

In last decade, China has constructed the most tall buildings, bridges and railways in the world, and educated the greatest number of engineering students, all of which requires advancement in Science, Engineering & Technology (SET).

Here we list 8 Great Ancient Bridges and 9 Grand Modern Bridges in China.

The way out of the trap of anxiety

Human life is a constant struggle, where happiness and sorrow follow each other like shadows. Human life is about happiness and sorrow, reunion and separation, easy and difficult situations, and illness and health, etc.


At some point in life, people are surrounded by worries. The sorrows accumulated in the heart hold the person's neck, which increases the person's worries even more.

When worries settle in a person's mind, his life becomes gloomy. He sees darkness even in the light of day, his hunger and thirst disappear, and the long silence of the night seems unbearable to him. It reduces the vitality of a person and causes premature old age.

Giving an idea of ​​the negative effects of worries, Ali (may Allah be pleased with him) said, "The strongest of your Lord's creations are mountains; and iron carves mountains.

Fire consumes iron. Water extinguishes fire. The clouds, which are controlled between the sky and the earth, carry water. The wind carries the clouds.

Man protects himself from the wind with his hands and moves within it to fulfill his needs. Intoxication affects man. Sleep prevails over intoxication. And worry prevents sleep. So the strongest of your Lord's creations is worry. (Mujamul Awsat)

Worry is a human characteristic. Therefore, it is natural for anyone to worry. It also came in the lives of Allah's beloved prophets sometimes. Our beloved Prophet Hazrat Muhammad (peace be upon him) used to be saddened by the rejection of his community, then Allah would comfort him. Prophet Yaqub (peace be upon him) lost his sight by crying in separation from his son Yusuf (peace be upon him), but he did not lose hope in Allah; rather, he trusted in Allah and asked for help from Allah. Therefore, a believer should seek help from Allah when he is worried. Below are some things to do when you are worried—

Faith and Taqwa: Whoever has complete trust and Taqwa in Allah, Allah Almighty will find a way out of any problem. The Holy Quran states, ‘Whoever fears Allah, Allah will find a way out for him.’ (Surah: At-Talaq, verse: 2)

Furthermore, if someone has complete faith in Allah, worry cannot have much effect on him, because he believes with all his heart that Allah Almighty will not do anything bad to him.

Recite Durood more: Reciting Durood on the Holy Prophet (PBUH) is the best balm to remove worry. Ubayy ibn Ka’b (may Allah be pleased with him) once informed the Holy Prophet (peace and blessings of Allah be upon him) about his frequent recitation of blessings, and the Holy Prophet (peace and blessings of Allah be upon him) said, “That will suffice for your worries and troubles, and your sins will be forgiven.” (Tirmidhi, Hadith: 2457)

Supplication and Istighfar: Crying out to Allah and making specific supplications in times of distress are also effective actions. Our Holy Prophet (peace and blessings of Allah be upon him) also used to seek refuge in Allah for relief from worries. He used to pray, “O Allah! I seek refuge in You from worry, anxiety, helplessness, laziness, cowardice, stinginess, debt, and being under the influence of people.” (Bukhari, Hadith: 6369)

Making the Hereafter the main goal: Whoever’s main concern is the Hereafter, Allah grants him freedom from want and the world becomes insignificant to him. But if it is the opposite, Allah makes the world narrow for that person.

(For details, see Tirmidhi, Hadith: 2465)

Being content with what you have: One day, the Messenger of Allah (peace be upon him) said to Hazrat Abu Zar (may Allah be pleased with him), Abu Zar, do you consider abundance of wealth as prosperity? Abu Zar (may Allah be pleased with him) said, Yes, O Messenger of Allah. The Messenger of Allah (peace be upon him) then said, Do you consider scarcity of wealth as poverty? He said, Yes, O Messenger of Allah. The Messenger of Allah (peace be upon him) said, Actually prosperity is prosperity of the heart, and poverty of the heart is real poverty. (Ibn Hibban: 685)

Therefore, a believer should be content with what he has. Be grateful to Allah in all circumstances. Insha Allah, Allah Almighty will reward him in this world and the Hereafter.

কেন আমায় ডা‌কো!



কেন আমায় ডা‌কো!
উষ্ণ হে‌সে নি‌রি‌বি‌লি
মতা‌নৈক্য হলেই
দোষা‌রোপ কত শাপ!
ডে‌কো না আমায়,
অ‌ন্যের ভালোয়
সব সময় মন সায় দেয়, ভাবায়
চ‌লে যে‌তে চায় আপন প‌থে
র‌বের খোঁ‌জে, নি‌জের কা‌ছে!
-- রাজ্জাক শাহ্
