I'm a hotel security guard. Foreigners often greet me and salute me at the gate, while China people.

This is a matter of national conditions, not to say that China people are not enthusiastic, because other countries have always done this in the hotel service industry, and foreigners are used to it, so it is the same for any hotel. This is the habit of others, and China people are definitely different. How many people could afford a hotel before? In one case, they have the courage to enjoy high courtesy, but they don't live every day and spend so much money. I think giving money should be enjoyed. This is the custom of China people.
