Xiangfu Fu son clothing company invited Wu Bridge for the creation of the theme song

In recent years, the talented mainland Chinese music producer Wu Duqiao has drawn much attention from the public. It is highly sought after by all walks of life. Wu Chung-chiao had just returned to Beijing as a new single for grassland singer Chang Jingwei [returning to grassland mother] after recording. This trip to Guangzhou, Wu Bridge is to accept the Guangzhou City Fu Xiang Fu Clothing Co., Ltd. President Passion invited to create a business theme song. When Wu Qunqiao arrived in Guangzhou, he and Mr. Zhan Songcheng saw each other as they used to be and they talked very well, just like friends they had not met for many years. Almost immediately, they started to write. In today's society, all walks of life are highly competitive, all businesses in order to enhance their market competitiveness, and strive to create their own brand image. Some businesses spared no expense to customize corporate songs for their own businesses to inspire staff unity, progress and innovation. Guangzhou Fu Xiang Fu Clothing Co., Ltd, many years ago have their own brand image, the product loved by the vast number of consumers. At present, the business song of Guangzhou Fu Xiang Zi Garments Co., Ltd. has been recorded successfully.

Nuts

A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.

In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in conjunction with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads.

Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand. While rare today[when?] due to the reasons stated below for the preference of hexagonal nuts, they are occasionally used in some situations when a maximum amount of torque and grip is needed for a given size: the greater length of each side allows a spanner to be applied with a larger surface area and more leverage at the nut.

The most common shape today is hexagonal, for similar reasons as the bolt head: six sides give a good granularity of angles for a tool to approach from (good in tight spots), but more (and smaller) corners would be vulnerable to being rounded off. It takes only one sixth of a rotation to obtain the next side of the hexagon and grip is optimal. However, polygons with more than six sides do not give the requisite grip and polygons with fewer than six sides take more time to be given a complete rotation. Other specialized shapes exist for certain needs, such as wingnuts for finger adjustment and captive nuts (e.g. cage nuts) for inaccessible areas.

A wide variety of nuts exists, from household hardware versions to specialized industry-specific designs that are engineered to meet various technical standards. Fasteners used in automotive, engineering, and industrial applications usually need to be tightened to a specific torque setting, using a torque wrench. Nuts are graded with strength ratings compatible with their respective Bolts; for example, an ISO property class 10 nut will be able to support the bolt proof strength load of an ISO property class 10.9 bolt without stripping. Likewise, an SAE class 5 nut can support the proof load of an SAE class 5 bolt, and so on.
