Double Happiness is undoubtedly very well-known, and once became the national cookware brand in Chinese mainland in the eighties and nineties of the last century, and the constantly rotating and creaking pressure weights have also accompanied the growth of two generations.
 
Shuangxi's predecessor was established in 1956 Shenyang Liming Aluminum Products Factory, in 1964 produced the first domestic pressure cooker, and in 1990 developed the first electric pressure cooker in the mainland, until the end of the last century, Shuangxi has been the leading brand of domestic cookware.
 
But today's Double Happiness has a sense of heroic twilight, whether it is a traditional pressure cooker or an electric pressure cooker has shown a decline, especially in the household pressure cooker market, Double Happiness's ultra-low price marketing strategy is no longer attractive to ordinary urban families, so now the main focus of Double Happiness pressure cooker is on commercial business places such as restaurants.
 
CYLC3601R is Double Happiness for restaurants and canteens to launch products, made of aluminum alloy, providing 11.5L, 13.5L, 16.5L, 25L, 33L, 50L six capacity options, from the capacity can also be seen, this is not for family users to prepare, its exaggerated volume and low price of about 400 yuan are extremely suitable for canteens, restaurants and other business places, for this kind of place, perhaps no brand can be more suitable than Double Happiness.
 
In the household market, Double Happiness also provides some products, but the number is not much, mainly LM-02AF20 and SXCY-24S01. LM-02AF20 is the most life-like product of the last century, that is, the type of pressure cooker used by countless post-80s children, supported by aluminum alloy, extremely rough workmanship, but the price is as low as 79 yuan. Another SXCY-24S01 is one of the few household stainless steel pressure cookers under Double Happiness, with a total of 4L, 5L, 6.5L, and 8L four capacities to choose from, and the price is 259 yuan.
