I would say using wechat isnt all bad, it depends on luck. Its as Bro etsys mentioned, need to be street smart if you have any intention to use wechat to get girls.
In fact I found a gem on my previous trip. Slim, good looking and outstanding gfe. I was sceptical initially when she sent me greeting first but the usual SOP, confirm she no ladyboy, video call, meet at hotel lobby, test 1 pop for service (3k ST). Due to her good service and gfe, I asked if she’s ok to accompany me throughout my trip. She replied ok, at the cost of 5k per day.
Same night, we went out party at Megadance and she asked if her bff can join us. I told her go ahead, ask you friend along to enjoy and party. We drank, dance and joke around. Pretty much high at about 3-4am, then my girl told me her bff asked if she can join us for 3p. Wow jackpot!!
So.. Basically the 2 girls accompanied me throughout the rest of my trip.
