The welcome speech of the tour guide is not a simple polite greeting, but actually a university question. First of all, greetings and welcome to the beautiful Spring City. Everyone has worked hard. I'll be at your service during my few days in Kunming. What's my name? You can call me whatever you want. Next, briefly introduce the characteristics of Kunming: the four seasons are like spring, so it is called Spring City, and introduce the average temperature, altitude and population in the next year. Then it is time to introduce the general situation of Yunnan. Introduce the multi-ethnic situation in Yunnan. Yunnan is a mineral kingdom, a non-ferrous metal kingdom, a plant kingdom (paving the way for leading the shopping and promoting Chinese medicine in the future) and an animal kingdom. Introduce Yunnan's flavor snacks, local conditions and customs. Don't forget to introduce that Kunming is the largest jewelry distribution center in China (paving the way for leading a team to buy jade in the future). If you have plans to buy tea, you should pave the way in advance now, but leave no trace. Finally, introduce the team's itinerary and accommodation in Kunming, and that's almost it. Finally, if there are many young people in the team, tell two yellow jokes to arouse the atmosphere, OK, so this is the opening remarks.
