![]() In the Song dynasty, especially during the Southern Song dynasty (1127–1279), with its capital situated in Lin'an (present-day Hangzhou), Lin'an became the biggest city in East Asia with a population more than 1.5 million, and the economic status of the Yangtze Delta became more enhanced. During the mid to late period of the Tang dynasty (618-907), the region emerged as an economic centre, and the Yangtze Delta became the most important agricultural, handicraft industrial and economic centre for the late Tang dynasty. Since the ninth century, the Yangtze Delta has been the most populous area in China, East Asia, and one of the most densely populated areas of the world. In these periods, there were several concomitant states or empires in China and each one had its own capital. ![]() Nanjing first served as a capital in the Three Kingdoms period as the capital of Eastern Wu (AD 229–280). The ancient Suzhou was the capital of the Wu state (12th century BC–473 BC), and the ancient Shaoxing was the capital of the Yue state (20th century BC?–222 BC). Other key cities of the region in pre-modern times include Suzhou and Shaoxing. Hangzhou served as the Chinese capital during the Southern Song dynasty (1127–1279), and Nanjing was the early capital of the Ming dynasty (1368–1644) before the Yongle Emperor moved the capital to Beijing in 1421. Since the fourth century, when the national capital was moved to Jiankang (present-day Nanjing) at the start of the Eastern Jin dynasty (AD 317–420), the Yangtze Delta has been a major cultural, economic, and political centre of China. With about a sixth of China's population and a fourth of the country's GDP, the YRD is one of the fastest growing and richest regions in East Asia. It covers an area of around 350,000 square kilometres (140,000 sq mi) and is home to over 240 million people. The urban build-up in the area has given rise to what may be the largest concentration of adjacent metropolitan areas in the world. In 2021, the Yangtze Delta had a GDP of approximately US$4.3 trillion, about the same size as Japan. Having fertile soil, the Yangtze Delta abundantly produces grain, cotton, hemp and tea. The area lies in the heart of the Jiangnan region (literally, "south of the River"), where the Yangtze River drains into the East China Sea. If that was all I could ever use that would suit me just fine.The Yangtze Delta or Yangtze River Delta ( YRD, Chinese: 长江三角洲 or simply Chinese: 长三角) is a triangle-shaped megalopolis generally comprising the Wu Chinese-speaking areas of Shanghai, southern Jiangsu, northern Zhejiang and northern Jiangxi. To answer the original poster, yes K&H are top quality. This particular dead fir was sky bound and I had to darn near push it to the ground. However I've also been cutting wedges out of fir limbs by truck headlights when I ran out of wedges. I carry more wedges in my truck tool box than some saw shops have in inventory. ![]() The bigger snags, say 48" DBH and larger can use lots of wedges to push over. One of my jobs is falling snags in the Sierras and sometimes in the SF Bay area. I've never felt the need for a slegde hammer though at times a 36" helve would be nice. This combo works very well especially when falling one tree of a tight grove where a longer handle is clumsy. Finally at times a carry a miner's axe which has a 3 1/2 lb head on an 18" helve. One of my bar scabbards for a 24/25" bar holds a boy's axe, a 2 1/4lb head with 28" fawns foot helve so on occasion that axe is my wedge driver. The length of the helve is personal and since I'm just over 5'8" 28" fits me well. Mine has a 28" helve and fits upside down in an aluminum scabbard which sits at the small of my back. It is made by Council and sold by Madsen's. My normal wedge driver is a 4lb single bit axe designed for falling (rafting) and has a polished poll. The barbs may be a gimmick but then again maybe not. I like trying different things like wedges to see how they work. A few days ago I bought 2 eight inch barbed wedges who's name escapes me right now. I prefer texturing on both sides vs one side smooth. They just have to live in the truck tool box rather than in my pouch.Īll the rest have never given me problems. The HardHead means you have to be wearing safety glasses and of course they are heavy but for problem trees the big HardHeads can't be beat. The green Bailey's is too mushy and even though they are soft pieces break off. The Black Bear have a very small head that is easily damaged so I would not buy them again even though in very small trees they do stay in the cut better than any other wedge I've used. I also have some Double Taper, K&H, Black Bear, HardHead (both types), and some green Bailey's. I use a variety of wedges, lately mostly Madsen's blue wedge which is made by Piller, the same people who make Double Taper.
