Blessed bag marketing is a marketing method of Japanese department stores in the new year. Merchants put many goods into cloth bags or cartons for matching sales. This kind of bag or carton is also called "blessing bag". This sales method is said to have originated from Matsuya Department Store in Ginza, Tokyo in the late Meiji period.

Usually, the contents of the blessing bag will not be made public in advance, but the goods generally belong to the same category. For example, in the blessing bags of digital cameras sold in home appliance stores, there are often other small household appliances besides digital cameras. In terms of price, the value of goods in the blessing bag is generally higher than its price tag. For example, a blessing bag of 65,438+00,000 yen may contain goods of 80,000 yen or 90,000 yen. Although the content of the blessing bag will not be made public in principle, in recent years, many high-priced blessing bags, such as jewelry or high-end home appliances, will be publicly matched with goods sold in advance, or give consumers a certain choice. In addition, in order to meet the needs of consumers to understand the contents of the blessing bag, some merchants will also launch transparent blessing bags.

"Webcast" can be roughly divided into two categories. One is to provide TV signals to watch on the Internet, such as live broadcasts of various sports competitions and cultural activities. The principle of this live broadcast is to convert TV (analog) signals into digital signals through collection, input them into computers, and upload them to websites for people to watch in real time, which is equivalent to "Internet TV"; The other is the well-known "webcast": independent signal acquisition equipment (audio+video) is set up on the spot and imported into the pilot terminal (pilot equipment or platform), and then uploaded to the server through the network and published on the website for people to watch.
