An example of insufficient scientific and technological level.

At present, the input of grassland animal husbandry has been seriously insufficient, and the relative support has slowed down or even declined, which has led many forage machinery manufacturing enterprises to switch production or stop production. In addition, there is a gap in technology, manufacturing means and technology between China and developed countries such as Europe and America, and the manufacturing capacity and level have been further expanded. For example, the existing forage machinery manufacturing enterprises have low product quality, many use failures and poor reliability. Reciprocating lawn mower needs sharpening for half a day, and its reliability is less than 80%. After 400 hectares of operation, the tooth breaking rate of foreign harrows is only about 4%, while the tooth breaking rate of China products is about 25% under the same workload.

Under the same operating conditions, the work of forage picking and palletizing in China is half that of similar foreign models.

An example in which the national quality is not high enough.

The National Tourism Administration lists "telling dirty jokes, spreading fabricated political jokes, and being keen on vulgar tastes", "going shirtless in front of others, wearing pajamas outside the room, and improperly dressed" and "doodling around cultural relics and historical sites" as unacceptable uncivilized behaviors in China, while "stepping into pornographic places and participating in gambling activities"; "Playing and joking in churches, temples and other religious places, not respecting the customs of local residents"; "Bargaining in uncompromising shops and forcing foreigners to take photos" is also one of the common uncivilized behaviors in foreign travel.

"No Smoking" written in simplified Chinese is hung in restaurants in Chiang Mai, Thailand; "Don't make noise" is hung on the streets of Paris, France; "Don't cut in line", "China people, please flush after defecation", "Please be quiet" and "Please don't spit everywhere" are hung in subway stations in new york, USA ... These warning signs marked in simplified Chinese can be seen everywhere in Germany, Japan, Thailand and Singapore.
